Abstract
Flame retardant compositions for cable jacketing and wire insulation that contain: (a) polyvinyl chloride resin; (b) a pentaerythritol ester plasticizer; (c) aluminum trihydrate; (d) antimony trioxide flame retardant; (e) a brominated phthalate ester; (f) isodecyl diphenyl phosphate plasticizer; and (g) zinc borate flame retardant and that are free of chlorinated polyvinyl chloride resin are disclosed.
Claims12
A flame retardant composition for cable jacketing and wire insulation comprising (in amounts based upon 100, by weight, parts of polyvinyl chloride):
- (a) 100 parts polyvinyl chloride resin;
- (b) about 10-50 parts of an ester plasticizer that is the reaction product of a polyol consisting essentially of pentaerythritol and a mixture of fatty acids having an average carbon number of about 6.7;
- (c) about 50-80 parts of aluminum trihydrate;
- (d) about 1-10 parts of antimony trioxide flame retardant;
- (e) no greater than 15 parts of a brominated phthalate ester;
- (f) about 2-20 parts of isodecyl diphenyl phosphate plasticizer;
- and
- (g) about 1-5 parts of zinc borate flame retardant,
- said composition being free of chlorinated polyvinyl chloride resin.
A flame retardant composition for cable jacketing and wire insulation comprising (in amounts based upon 100 parts, by weight, of polyvinyl chloride):
- (a) 100 parts polyvinyl chloride resin;
- (b) about 10-50 parts of an ester plasticizer that is the reaction product of a polyol consisting essentially of pentaerythritol and a mixture of fatty acids having an average carbon number of about 6.7, wherein said fatty acids are selected from the group consisting of valeric, caproic, enanthic, caprylic, pelargonic, and caproic acids;
- (c) about 50-80 parts of aluminum trihydrate;
- (d) about 1-10 parts of antimony trioxide flame retardant;
- (e) about 1-15 parts of a brominated phthalate ester;
- (f) about 2-20 parts of isodecyl diphenyl phosphate plasticizer;
- (g) about 1-5 parts of zinc borate flame retardant;
- (h) about 5-30 parts of a filler;
- (i) about 3-10 parts of a basic lead heat stabilizer;
- and
- (j) about 0.1-0.5 parts of a stearic acid lubricant,
- said composition being free of chlorinated polyvinyl chloride resin.
