Abstract
A polymeric matrix including: 50 to 80%, preferably 64 to 73% PET; 18 to 50%, preferably 20 to 28% of a mixture of polyolefins; 0.1 to 15%, preferably 0.5 to 7% of at least one flame-retardant additive; 0 to 2%, preferably 0.2 to 1% of at least one antioxidant; 0 to 2% preferably 0.2 to 1% of at least one crosslinking promoter; 0 to 2%, preferably 0.2 to 1% of at least one anti-hydrolysis agent, the percentages being by weight of the total weight of the matrix. Also, the use of polymeric matrix in manufacturing electrical cables.
Claims14
A polymeric matrix comprising:
- 50 to 80% Poly(ethylene terephthalate) (PET), the PET comprising over 50% by weight of recycled PET;
- 18 to 50% of polyolefins, the polyolefins consisting of a mixture of ethylene methyl acrylate copolymer and of ethylene/methyl acrylate/glycidyl methacrylate terpolymer;
- 0.1 to 15% of flame-retardant additives, the flame retardant additives consisting of a mixture of antimony trioxide and decabromodiphenyl ethane;
- 0.2 to 1% of antioxidants, the antioxidants consisting of a mixture of pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate), 2′,3-bis[3-[3,5-di-tert-butyl-4-hydroxyphenyl]propioyl] propionohydrazide, and dioctadecyl 3,3′-thiodipropionate;
- 0 to 2% of at least one crosslinking promoter;
- and
- 0 to 2% of at least one anti-hydrolysis agent,
- the percentages being by weight of the total weight of the matrix.
