  • Electrical insulating vinyl halide resin compositions
    Patent number: 5439742
    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.
