A composition comprising:
- (a) 100 parts polychloroprene-based polymer, comprising
- (i) polychloroprene co-polymer;
- and
- (ii) polychloroprene homopolymer;
- wherein the ratio of (i) to (ii) is between 20:80 and 80:20;
- (b) 30-90 parts flame retardant;
- and
- (c) 3-9 parts curing agent.
5 more elements
A composition comprising:
- (a) 100 parts polychloroprene-based polymer, comprising
- (i) about 60 parts polychloroprene co-polymer;
- and
- (ii) about 40 parts polychloroprene homopolymer;
- (b) 50-70 parts flame retardant, wherein the flame retardant comprises one or more of aluminum trihydroxide, chlorinated paraffin wax, antimony oxide, decabromo diphenyl ether, and zinc borate;
