Claims
- 1. A composition of matter comprising polyvinyl chloride resin, a plasticizer consisting essentially of 45 to 60 parts by weight per 100 parts polyvinyl resin of a char-forming flame retardant phosphate plasticizer, said plasticizer including 30-60% by weight of tributoxyethyl phosphate, or 85-100% by weight 2-ethylhexyl diphenyl phosphate, 4-8 parts by weight of a di-epoxycycloaliphatic carboxylate and 2-4 parts by weight of a metallic stabilizer and wherein said composition is free of phthalate plasticizer.
- 2. An electrical cord comprising:
- (a) a plurality of conductor strands;
- (b) an electrically insulating coating of each conductor;
- (c) a char-forming, flame retardant phosphate plasticized PVC resin composition jacket over the conductors and coating said composition comprising:
- (a') PVC resin; and
- (b') a plasticizer consisting essentially of 45-60 parts by weight per 100 parts PVC resin of a char-forming flame retardant plasticizer including 30-60 weight percent tributoxyethyl phosphate, 4-8 parts by weight of a compatible di-epoxycycloaliphatic carboxylate and 2-4 parts by weight of a metallic stabilizer.
- 3. A composition of matter comprising polyvinyl chloride resin, a plasticizer consisting essentially of 45 to 60 parts by weight per 100 parts polyvinyl resin of a char-forming flame retardant phosphate plasticizer, said plasticizer including 30-60% by weight of tributoxyethyl phosphate, 4-8 parts by weight of a di-epoxycycloaliphatic carboxylate and 2-4 parts by weight of a metallic stabilizer.
- 4. The composition recited in claim 3 wherein said plasticizer includes a diaryl phosphate or a triaryl phosphate.
- 5. The composition recited in claim 4 wherein said di-epoxycycloaliphatic carboxylate is 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylate and the metallic stabilizer is a phosphite chelator containing barium, cadmium and zinc therein.
- 6. The composition recited in claim 4 including a lubricant, a U-V light stabilizer and an anti-plate-out additive.
