Problems solved by technology
[0006] Furthermore, such coverings usually exhibit several disadvantages: they are difficult to cut, their flexibility is reduced compared to uncovered FEF foams, causing difficulties and delays in installation
[0009] This material should be the preferred product choice in terms of fire performance and smoke formation, but because of the higher thermal conductivity (according to EN12667) compared to the above mentioned NBR based FEF ( Ultima:≤0,040W / m*K0℃; ≤0,033W / m*K0℃), lower water vapor transmission resistance (according to EN12086WVT value: Ultima:≥7.000; ) and higher cost (not limited to because of higher density), its application field is limited

Embodiment Construction
[0052] The following examples and comparative examples were prepared in a three-step production process: mixing compound, extrusion process, and expansion and crosslinking.
[0053] In-house batch mixer (Banbury Mixer) with an average mixing time of 10 minutes and an average discharge temperature of 140°C. The compound was further homogenized on a roller mill, after cooling the compound to less than 90°C, the blowing agent and crosslinking system were added to the roller mill.
[0054] Extrusion is performed in a ribbon-fed single-screw vacuum extruder to provide unexpanded and unvulcanized sheet and tube. They were then crosslinked and expanded into sheets with a wall thickness of 25 mm and tubes with a wall thickness of 25 mm and an inner diameter of 22 mm in a hot air oven of 5 ovens in series. Table 1 shows the starting materials used for the compounds. Table 2 shows an overview of all tested materials. Table 3 shows the formulations of the inventive examples (compoun...

Abstract
The present invention relates to an expanded polymeric material which consists of at least 300 phr, but less than 1000 phr ingredients in total, comprising 100 phr of at least two polymers, of which 1) at least 55 phr is polyvinyl chloride (PVC) or vinyl chloride copolymer or vinyl chloride terpolymer or a mixture thereof and 2) at least 10 phr is at least one additional chlorinated organic polymer that is crosslinked by sulphur and / or metal oxides and / or thiadiazoles, to the process of manufacturing such a material, and to the use of such a material.
Description
technical field [0001] The present invention relates to a material for thermal and / or acoustic insulation comprising a polymer based on PVC (polyvinyl chloride) and / or vinyl chloride copolymers and / or vinyl chloride terpolymers and at least one other chlorinated organic polymer Expanded polymers (blends) of materials, methods of making such materials and applications relating to such materials. Background technique [0002] Flame retardancy and smoke suppression play an important role in insulating products, especially when such products are used in houses and especially public buildings. Furthermore, smoke suppression concerns for insulating materials became even more important when the Single Body Burn Test (SBI-Test) was implemented and became mandatory within the EU. This test primarily classifies 3 aspects of combustion behaviour: flame spread / heat release, smoke production and burning particles / drips. The SBI-test (ENISO 13823) replaces the previous national test for...
