[0002] Profile arrangement

[0003] The invention relates to a profile arrangement, in particular an edge strip for furniture panels, with at least one core strip made of at least one preferably halogen-free polymeric material, wherein the core strip has a front side and a back side opposite it, according to the preamble of claim 1. The invention further relates to the technical field of objects such as furniture panels and the like with at least one such profile arrangement.

[0004] These types of profile arrangements have primarily been used to decorate the narrow sides / edges of objects such as furniture panels, wood-based panels, and particleboard, but increasingly also doors, walls, ceilings, floors, stair railings, handrails, and the like. For this purpose, the profile arrangements are fixed to the narrow sides / edges of the objects to be decorated, for example, using a hot-melt adhesive or an adhesive-free laser process. Through a specific selection of materials, these profile arrangements can be adapted to achieve a desired appearance, for example, with regard to the edge of the corresponding furniture component.

[0005] However, the visual impression achievable with existing profile arrangements cannot always satisfy the ever-increasing demands on the appearance of modern objects such as furniture, especially when new functions, designs, or surfaces are desired for the profile arrangements. It was therefore necessary to optimize or modify the materials used so far to enable new functionalities, designs, and surfaces.

[0006] The invention is therefore based on the objective of overcoming the disadvantages of the prior art and providing profile arrangements that, on the one hand, make it possible to achieve a high-quality optical and tactile impression and retain the existing functions from the prior art, and on the other hand, include new functionalities, preferably halogen-free, and are also economical and, in particular, sustainable to manufacture. REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0007] According to the invention, this problem is solved by the features of claim 1.

[0008] Further advantageous embodiments are described in the dependent claims.

[0009] According to the invention, a profile arrangement, in particular an edge strip for furniture panels, is provided with a polymeric, preferably halogen-free, strip core, wherein the material of the strip core comprises:

[0010] 50 to 95 wt.%, preferably 55 to 95 wt.%, particularly preferably 60 to 90 wt.%, based on the total weight of components (A) and (B), of a polymeric component (A),

[0011] 5 to 50 wt.%, preferably 5 to 45 wt.%, particularly preferably 10 to 40 wt.%, based on the total weight of components (A) and (B), and a further polymeric component (B),

[0012] wherein the ratio of the melt flow index (MFI) of component (A) to the melt flow index (MFI) of component (B) is at least 5, preferably at least 20, preferably at least 30, in particular at least 50, e.g. at least 100 according to DIN ISO 1133-1:2022-10 measured at 230 °C / 21.6 kg.

[0013] The ratio can be 5 to 5,000, e.g., 30 to 5,000, preferably 50 to 3,500, more preferably 100 to 3,000, more preferably 250 to 2,500, more preferably 400 to 2,000. For example, the ratio can be approximately 5 to 3,500, e.g., 10 to 3,000, or more preferably, approximately 10 to 2,000. However, it can generally be advantageous if the ratio does not exceed 5,000, e.g., 3,000, or 2,000. The weight fraction of components (A) and (B) together in the material of the strip core is advantageously more than 50%, e.g., at least 70%, e.g., at least 80%, e.g., at least 90%, e.g., at least 95%. That is, the core of the strip preferably consists at least predominantly of components (A) and (B). Thus, according to the invention, two polymeric materials with very different MFIs are combined. Here, component (A) has a significantly higher MFI than component (B), i.e.,Component (A) has significantly better flow properties than component (B), meaning it is considerably less viscous than the comparatively very viscous component (B). This can surprisingly result in, for example, a striped or even a schlieren appearance in the core of the strip, i.e., in the base material of REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 dr. schie / rin.

[0014] A profile strip (especially an edge strip) is produced, and optionally a corresponding tactile quality. This is based on the very different flow properties of the two components (A) and (B). Since, according to the invention, the strip core, and thus the core material of the profile body, has a corresponding matrix and therefore a corresponding appearance in the cross-section, this appearance is retained even in the milled area, for example in the area of ​​a corresponding milling radius or chamfer, after milling, when flush milling an edge strip with the furniture panel in the usual way. Thus, the otherwise common, and especially with multi-colored decors, disadvantageous "picture frame effect" in the milled transition area between the surface of the furniture panel and the profile body, especially the edge strip, can be avoided according to the invention.

[0015] Surprisingly, it was found that the preferably halogen-free polymeric material of the strip core, in this configuration, can be processed into profile arrangements easily and with high quality using known extrusion, co-extrusion, or post-co-extrusion processes. During extrusion, component (B) flows significantly faster than component (A) due to its considerably lower MFI, resulting in the aforementioned strip or...

[0016] A striation effect results. Advantageously, a profile arrangement can be provided that not only achieves the previously known functional effects, for example, against moisture or temperature, but is also capable of exhibiting a visually novel, perceptible structural effect when used as intended. This effect, particularly when the profile arrangement is attached to a furniture panel and adapted / milled along its long edges, creates a completely new panel appearance. Surprisingly, an optical and / or tactile transition in terms of the decor between the furniture panel and the profile arrangement attached to the end face (in this case, the edge trim) is no longer perceptible, or at least only significantly reduced (no "picture frame effect"). All of this is achieved through the very different flow behavior of the two components (A) and (B).Another advantage of the profile arrangement is that the material price as well as the manufacturing costs are at a very low level, with at the same time better availability of the required raw materials, so that this profile arrangement has a significantly lower "CCh footprint" than the profile arrangements in the known prior art.

[0017] A further advantage of the profile arrangement is that, surprisingly, it is possible to use the profile arrangement as intended without an additional REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0018] A functional layer, particularly an adhesion promoter layer, is applied to and fixed to the end face of objects such as furniture panels, furniture pieces, doors, chipboard, worktops, and the like. The profile arrangement is therefore highly versatile and can be applied to various objects such as furniture panels, furniture pieces, doors, chipboard, worktops, and the like. In addition to protecting the narrow side / end face of, for example, a furniture panel, it also allows for improved visual and design aspects.

[0019] A further advantage of the profile arrangement is that component (A) and / or component (B) is based on polyolefin, such as polypropylene (PP) or polyethylene (PE); a styrene-based polymer, such as polystyrene (PS) or styrene-butadiene copolymer with a predominant styrene content (SB) or acrylonitrile-styrene-acrylate copolymers (ASA) or acrylonitrile-butadiene-styrene copolymers (ABS) or styrene acrylonitrile (SAN);

[0020] polybutylene terephthalate (PBT); polyethylene terephthalate (PET); polyoxymethylene (POM); polyamide (PA); polymethyl methacrylate (PMMA); polyphenylene oxide (PPO);

[0021] Polyetheretherketone (PEEK); Polyphenylene sulfide (PPS); Liquid Crystal Polymer (LCP); Polyamide-imide (PAI); Polyphenylsulfone (PPSU); Polyaryletherketone (PAEK); Polyacrylonitrile (PAN); Polychlorotrifluoroethylene (PCTFE); Polyetherketone (PEK); Polyimide (PI); Polyisobutene (PIB); Polyphthalamide (PPA); Polypyrrole (PPY); Polytetrafluoroethylene (PTFE); Polyurethane (PUR) and mixtures of at least two of these materials. This makes the profile arrangement economically and, in particular, sustainably manufacturable using the various materials.

[0022] Another advantage of the profile arrangement is that the polymeric material of the strip core has

[0023] Component (A) 50 to 95 wt.%, preferably 55 to 95 wt.%, particularly preferably 60 to 90 wt.%, based on the total weight of components (A) and (B), a polyolefin, preferably a polypropylene (PP), wherein the polyolefin has a melt flow index (MFI) of 300 to 500 g / 10 min., preferably 320 g to 450 g / 10 min., as measured at 230 °C / 21.6 kg according to DIN ISO 1133-1:2022-10.

[0024] and

[0025] Component (B) 5 to 50 wt.%, preferably 5 to 45 wt.%, particularly preferably 10 to 40 wt.%, based on the total weight of components (A) and (B), a material based on polyolefins, preferably based on polypropylene (PP), wherein the polyolefin REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0026] has a melt flow index (MFI) of 0.1 to 50 g / 10 min., preferably 0.2 g to 45 g / 10 min., as measured according to DIN ISO 1133-1:2022-10 at 230 °C / 21.6 kg.

[0027] In this version, profile arrangements are available that are also very economical and, in particular, extremely sustainable to manufacture.

[0028] Furthermore, the profile arrangement is designed such that the polymeric material of component (B) has a density of 1.1 g / cm³. 3 up to 1.5 g / cm³ 3 , preferably 1.15 g / cm³ 3 up to 1.25 g / cm³ 3 , according to DIN EN ISO 1183-1: 2019-09.

[0029] In a further advantageous embodiment, the profile arrangement is designed such that the core of the strip and at least one narrow side of the profile arrangement have at least a partially structured surface.

[0030] It has also proven advantageous that the surface of the core of the strip and / or the surface of at least one narrow side has a mean roughness depth R. zfrom 0.3 pm to 15 pm, preferably 0.5 pm to 10 pm, particularly preferably 1 to 8 pm, preferably a maximum of 10 pm, preferably measured according to ISO 21920-2:2021-12. It is also advantageous that the surface of at least one narrow side of the profile arrangement has a mean roughness depth R after material removal machining. z preferably with a maximum thickness of 10 pm, preferably measured according to ISO 21920-2:2021-12. These advantageous configurations of the profile arrangement provide not only visually appealing surfaces / narrow surfaces but also tactile, tangible surfaces / narrow surfaces.

[0031] Another advantage of the profile arrangement is that the surface of the core of the strip has an L* value of at least 60, preferably at least 70, and particularly preferably at least 75, measured via a multi-angle measurement according to DIN 5033-7:2014-10 between -15° and 110°. This visually appealing surface is also surprisingly easily detectable via a multi-angle measurement of the L*a*b* color space. The L*a*b* color space as defined in this invention (also: CIELAB, CIEL*a*b*, Lab colors) describes all perceptible colors. It utilizes a three-dimensional color space in which the brightness value L* is perpendicular to the color plane (a*, b*). The a-coordinate indicates the hue and color intensity between green and red, and the b-coordinate indicates the hue and REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 dr. she / her

[0032] The color intensity lies between blue and yellow. The larger the positive a and b values, and the smaller the negative a and b values, the more intense the hue. If a=0 and b=0, an achromatic hue is present on the lightness axis. In typical software implementations, L (Lightness) can take values ​​between 0 and 100, and a and b can be varied between -128 and 127. In the standard 8-bit model per color channel, this results in 16.7 million possible Lab coordinates. The actual L*a*b* color space (our color perception) extends beyond these a / b limits in some areas and does not reach them in most. Among the most important properties of the L*a*b* color model are its device independence and its perceptual relevance, meaning that colors are defined as they are perceived by a normal observer under standard lighting conditions, regardless of the type of generation or reproduction technique used.

[0033] A further advantage of the profile arrangement is that component (B) has an AE* value (total color difference) of at least 3, preferably at least 5, and particularly preferably at least 10, relative to component (A) of the core strip, as measured by color measurement with sphere geometry (d / 8) according to DIN 5033-7:2014-10. It is also advantageous that no additional coloring / over-coloring is necessary, which would negatively affect the material cost of the profile arrangement. The aforementioned color difference ensures that the two components (A) and (B) are visually distinct from one another, so that the previously mentioned striped and / or streaked appearance of the core strip material achieves the desired visual effect.

[0034] It is also advantageous in the profile arrangement that the component (A) and / or the component (B) of the strip core has a recycled content according to DIN EN ISO 14021: 2021-10 of at least 5 to 50 wt.%, preferably 5 to 45 wt.%, particularly preferably 10 to 40 wt.%, based on the total weight of components (A) and (B).

[0035] It has also proven advantageous in the profile arrangement that the front surface of the strip core has a coating, at least in sections. A further advantage of the profile arrangement is that the coating on the front surface of the strip core has a thickness of 1 to 350 µm, preferably 2 to 300 µm, and particularly preferably 5 to 250 µm. It is also advantageous that the coating on the front surface of the strip core is designed as a co-extruded or post-co-extruded layer, as a paint application, or as a printed layer. This coating, designed as a paint application or printed layer, can advantageously be implemented. REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0036] In particular, this can be achieved through so-called multicolor printing, digital printing, gravure printing, and the like. In this advantageous embodiment, the intensity and feel of the profile assembly's surface can be further optimized by selecting the material, thickness, and shape of the coating. The coating can advantageously contain renewable raw materials from 0.01% to 100%, preferably 20% to 100%, and most preferably 40% to 100%. All of this leads to economical and cost-effective production of the profile assembly and to further optimization possibilities, especially for the surface and appearance of the profile assembly.

[0037] A further advantage of this profile arrangement is that the back of the strip core has a functional layer, at least in some sections. In addition to the economical and cost-effective manufacturing of the profile arrangement, it is also possible to optimize the fixation of the profile arrangement to an object by varying the functional layer. This can be achieved, for example, by designing the functional layer as a so-called adhesion promoter layer, a so-called hot melt adhesive layer, or a polymeric functional layer.

[0038] A further advantage of the profile arrangement lies in the fact that at least one cover layer with a thickness of 2 to 60 pm, preferably 5 to 30 pm, is arranged on the front surface of the profile body. It has also proven advantageous for the cover layer on the front surface of the profile core to comprise at least one acrylic polymer and to have a maximum transmittance of 80% for visible light across its thickness, measured according to DIN EN ISO 13468-2:2006-07. The cover layer can advantageously contain renewable raw materials of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%. In addition to an aesthetically pleasing top surface of the profile arrangement, mechanical protection can also be implemented, which, however, does not affect the appearance, in particular the optical structural effect of the profile arrangement.

[0039] The profile arrangement is further characterized by the fact that the halogen-free, polymeric material of the core of the strip has a tensile strength of at least 35 MPa, preferably at least 40 MPa according to DIN EN ISO 527:2019-12.

[0040] In a further advantageous embodiment of the profile arrangement, it has been shown that the back of the strip core of the profile arrangement can be subjected to a surface treatment by a REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 dr. schie / rin

[0041] The material has been subjected to corona treatment, flame treatment, plasma treatment, silicatization, and similar processes. This allows for an optimized bonding of the profile arrangement for a wide variety of material combinations.

[0042] In a further advantageous embodiment of the profile arrangement, it has been found that the halogen-free polymeric material of the core and / or the halogen-free polymeric material of the functional layer contains light- and / or radiation-absorbing additives in an amount of 0.01 to 5 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. In this embodiment of the profile arrangement, it can be optimally welded, for example on the narrow sides of furniture pieces, by laser welding processes known per se, through the targeted introduction of energy into the halogen-free polymeric material of the functional layer.

[0043] It has also proven advantageous that the halogen-free polymeric material of the core and / or the halogen-free polymeric material of the functional layer contains at least one additive, partially containing inorganic and / or organic pigments, in an amount of 0.01 to 5.0 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. This makes it possible to apply the profile arrangement cost-effectively and economically, for example, to the narrow sides of furniture, using all currently known radiation-activated methods.

[0044] Another advantage of the profile arrangement is that the core material comprises at least one filler in 5 to 50 wt.%, preferably 10 to 45 wt.%, and particularly preferably 15 to 35 wt.%, based on its total weight. The filler is selected, in particular, from silicates, carbonates, phosphates, sulfates, sulfides, and the like. It is further advantageous if the filler is selected from the group of layered silicates, as well as carbonates or sulfates of barium and calcium, and the like. In a particularly advantageous embodiment of the profile arrangement, the core filler comprises, in particular, barium sulfate, calcium sulfate, calcium carbonate, talc, and wollastonite. The fillers can advantageously comprise renewable raw materials in proportions of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%.

[0045] Furthermore, the profile arrangement is advantageously designed such that the halogen-free polymeric material of the core and / or the polymeric material of the functional layer contains at least one of the following additives: stabilizers to improve the REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0046] Resistance to light exposure, UV radiation, and weathering; stabilizers to improve thermal and thermo-oxidative resistance; stabilizers to improve hydrolytic resistance; stabilizers to improve acidolytic resistance; lubricants; demolding aids; color additives; crystallization-regulating substances and nucleating agents; flame retardants; impact modifiers; fillers; and / or plasticizers. The additives can advantageously comprise renewable raw materials from 0.01% to 100%, preferably 20% to 100%, and particularly preferably 40% to 100%. Thus, a profile arrangement can be provided that is both economical and cost-effective to manufacture, while also achieving the functions known from the prior art, such as adhesion strength, peel strength, and water resistance.

[0047] A further advantage of the profile arrangement is that component (A) and / or component (B) comprises renewable raw materials of at least 5 to 50 wt.%, preferably 5 to 45 wt.%, and particularly preferably 10 to 40 wt.%, as verified by mass balance analysis, e.g., via ISCC. For example, the profile arrangement, component (A) and / or component (B), can comprise 50% renewable raw materials certified by mass balance analysis, as well as 40% non-renewable, fossil-based raw materials.

[0048] Another preferred embodiment relates to a profile arrangement according to one of the previous embodiments, wherein the functional layer is based on a halogen-free polymeric material, preferably polypropylene (PP), acrylonitrile butadiene styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polyethylene (PE), styrene-ethylene butadiene styrene block copolymer (SEBS), polyamide (PA), thermoplastic olefin-based elastomer (TPO), thermoplastic urethane-based elastomer (TPU), thermoplastic copolyester (TPO), styrene block copolymers (SBS, SEBS, SEPS, SEEPS and MBS), thermoplastic copolyamide (TPA) and the like.

[0049] Component (A) and / or component (B) can advantageously comprise renewable raw materials of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%. This measure has the advantage that this material is readily available at low cost, easy to process, and also simple to chemically modify. In a further preferred embodiment, the functional layer is designed as a thermoplastic functional layer, which makes it possible to assemble a profile arrangement according to the previously described embodiments without adhesive, i.e., without directly before REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0050] In addition to attaching, a so-called hot melt adhesive is applied and the piece is fixed without a visible joint on one narrow side of a lightweight panel.

[0051] Furthermore, it has proven extremely advantageous that the material of the functional layer is selected from the group of polyurethanes (PUR), acrylates, epoxy resins, ethylene vinyl acetates (e.g. EVA dispersions), polyvinyl acetates (PVAC dispersions) and the like, as well as mixtures of two or more of the aforementioned substances.

[0052] A further advantage of the profile arrangement is that the functional layer material incorporates an adhesion promoter system, preferably in the form of aqueous dispersions or solutions in organic solvents of binder resins. These resins are selected in particular from the group consisting of polyurethanes, polyesters, acrylates, methyl methacrylates, epoxy resins, ethylene vinyl acetates, polyvinyl acetates, polyvinylidenes, natural rubber, and mixtures of two or more of the aforementioned binder groups. They can be used with or without the addition of crosslinking / activator components, e.g., based on polyisocyanates, amines, or peroxides. The halogen-free, polymeric material of the functional layer can be applied directly to the back of the core strip during the manufacturing of the profile arrangement.

[0053] It has also proven advantageous for the functional layer of the profile arrangement to have a thickness of 0.1 pm to 100 pm, preferably 0.2 pm to 75 pm, and particularly preferably 0.5 pm to 30 pm. This advantageously results not only in economical and cost-effective manufacturing of the profile arrangement, but also in the functional layer being optimally adaptable to the respective geometry of the profile arrangement.

[0054] The object of the invention, to provide an object, is achieved by an object such as a panel element, in particular a furniture panel, wood-based panel, worktop, chipboard, lightweight panel, interior finishing panel, door, fiber cement panel or the like, with at least one profile arrangement which has the advantageous embodiments of the previous sections.

[0055] The object, such as a panel element, in particular a furniture panel, wood-based panel, worktop, particleboard, lightweight panel, interior finishing panel, door, fiber cement panel, or the like, is further advantageously designed such that the profile arrangement is positioned on the object with a rear side facing away from the front. REHAU Industries SE & Co. KG Rehau, March 25, 2026 Int. Ref: 25.016 / 1 Dr. Schie / Rin

[0056] The object, such as a panel element, in particular a furniture panel, wood-based panel, worktop, chipboard, lightweight panel, interior finishing panel, door, fiber cement panel or the like, is further characterized by the fact that the profile arrangement has a peel strength of at least 30 N / cm according to DIN 53539:1979-09, measured on chipboard.

[0057] The invention further relates to a method for manufacturing a profile body according to claim 13.

[0067] wherein the ratio of the melt flow index (MFI) of component (A) to the melt flow index (MFI) of component (B) is 5 to 5,000, e.g. 5 to 3,500, preferably 50 to 3,500, further preferably 100 to 3,000, further preferably 250 to 2,500, further preferably 400 to 2,000 according to DIN ISO 1133-1:2022-10 measured at 230 °C / 21.6 kg.

[0068] In this embodiment, the combined weight fraction of components (A) and (B) in the core material 2 is at least 95%, meaning that the core material 2 contains a maximum of 5% by weight of other materials in addition to components (A) and (B). This also applies to all other embodiments shown in Figures 2 and 3. In this embodiment, the profile arrangement 1 is designed such that the halogen-free polymeric material of the core material comprises 260% by weight of component (A) and 40% by weight of component (B), with the ratio of the melt flow index (MFI) of component (A) to the melt flow index (MFI) of component (B) being approximately 1,600 according to DIN ISO 1133-1:2022-10, measured at 230 °C / 21.6 kg.

[0069] The profile arrangement 1 is further designed such that component (A) and / or component (B) is based on polyolefin, such as polypropylene (PP) or polyethylene (PE); a styrene-based polymer, such as polystyrene (PS) or styrene-butadiene copolymer with a predominant styrene content (SB) or acrylonitrile-styrene-acrylate copolymers (ASA) or acrylonitrile-butadiene-styrene copolymers (ABS) or styrene acrylonitrile (SAN);

[0138] In this embodiment, the thickness of the coating 6 is approximately 15 pm.

[0139] The object, such as furniture panel 10, is characterized in that the profile arrangement 1 is attached, and in particular fixed, to at least one end face 11 of the furniture panel 10. In this exemplary embodiment, the object, such as furniture panel 10, is designed such that the profile arrangement 1 is bonded, and in particular fixed, to the end face 11 of the furniture panel 10 without an additional functional layer, in particular an adhesion promoter layer. The object, such as furniture panel 10, is advantageously designed such that the profile arrangement 1, attached to the end face 11 of the furniture panel 10, has at least a radius 80° and / or at least one chamfer 90° on at least one of its end faces 8, 9 arranged in the longitudinal profile direction L.

[0140] With the aid of the teaching according to the invention, a striped or streaked appearance can also be achieved in the area of ​​the radius 80 and / or in the area of ​​the chamfer 90, and thus very well adapted to the appearance of the large surface of the furniture panel 10. The otherwise usual, acceptable "picture frame effect" in the area of ​​the radius 80 or chamfer 90, which results from the edge milling (as shown in Fig. 3) of the edge strip 1, can thus be eliminated by means of the teaching according to the invention. The aforementioned "striped or streaked effect" is based on an incomplete mixing of components (A) and (B) during the manufacturing process of the profile arrangement 1.
