Abstract
Electrical insulating compositions of vinyl halide resins (PVC) are formulated to contain a polymeric metal aromatic polycarboxylate as an electrical insulating additive. For example, polymeric calcium terephthalate is used in minor amounts of about 0.2 to 0.5 phr PVC to provide an excellent insulating effect. Lead stabilizers may be avoided in the polymer compositions and, instead, nontoxic metal salt heat stabilizers such as calcium, barium, zinc, etc., may be used.
Claims12
An electrical insulating vinyl halide resin composition comprising a vinyl halide resin, a metal compound stabilizer selected from a group consisting of antimony, barium, cadmium, calcium, zinc and mixtures thereof for said resin and a polymeric polyvalent metal aromatic polycarboxylate polymeric calcium terephthalate as an electrical insulating agent in an effective electrically insulating amount.
An electrical insulating vinyl halide resin composition comprising a polymer or copolymer of vinyl chloride, a metal salt of a higher fatty acid selected from the group consisting of zinc, cadmium, tin, calcium, strontium, barium, and antimony, and mixtures of said metal salts, and a polymeric polyvalent metal aromatic polycarboxylate polymeric calcium terephthalate as an electrical insulating agent in an effective electrically insulating amount.
