Problems solved by technology

[0011] These disadvantages have limited the use of alternative plasticizers such as epoxidized soybean oil as primary plasticizers with necessary compatibilizers, see for example U.S. Patent Application Publication No. 2011 / 0272174
[0012] Alternatively, alternative plasticizers have limited use as secondary plasticizers based on compositions present only in small amounts in vinyl chloride polymer compositions, see for example U.S. Patent Application Publication No. 2010 / 0010127

example 1

[0140] Example 1: Chemical structures of plasticizers used in PVC1-PVC5. The chemical structure of ESO can vary so Example 1 shows only one example of an ESO molecule.

[0141] 2. Test steps and methods

[0142] 2.1 Preparation of "Additional layer elements comprising second composition", here polyethylene samples

[0143] Both base resin and catalyst were obtained in pellet form and were dry mixed at a ratio of 95 wt% base resin to 5 wt% catalyst. After mixing, the material was extruded through a Collin belt extruder with a 1 mm die. For LDPE materials (PE1-PE5), the temperature set on the extruder (from injection to molding) is 60°C-150°C-160°C-170°C-170°C. LLDPE material (PE6) is extruded at a temperature setting of 60°C-160°C-180°C-220°C-225°C. The resulting tape was about 0.40-0.45 mm thick and was placed and stored in a refrigerator after extrusion to prevent surrounding cross-linking. In the next step, the tape was placed in a 200×200 mm frame and pressed to a thic...

Abstract

The present invention relates to a cable construction comprising one or more layer elements, which layer elements comprise a first composition, wherein the first composition comprises: 20 to 80 weight percent of a vinyl chloride resin and 1 to 40 weight percent of an epoxidized ester of fatty acids and a monomeric polyol, which epoxidized ester is a compound of formula (I) wherein the compound of formula (I) has an amount of double bonds corresponding to an Iodine value of 2 or less, a power cable, process for producing a cable construction, and a crosslinked cable construction obtainable by the process.

Description

technical field [0001] The present invention relates to a new cable construction comprising one or more layer elements comprising a first composition, wherein said first composition comprises: [0002] 20 to 80 weight percent vinyl chloride resin and 1 to 40 weight percent epoxidized esters of fatty acids and monomeric polyols, said epoxidized esters being compounds of formula (I), [0003] [0004] said compound of formula (I) contains a number of double bonds corresponding to an iodine value of 2 or less, [0005] The invention also relates to a power cable, a method for producing a cable construction and a crosslinked cable construction obtained by said method. Background technique [0006] Vinyl chloride polymer compositions, such as polyvinyl chloride (PVC) compositions, are well known in the art. Vinyl chloride polymer compositions without plasticizers tend to be rigid and can be used in the manufacture of rigid products such as pipes and tubing. Vinyl chloride p...
