A flame retardant low smoke PVC-based thermoplastic composition for use in wire insulation and cable jacketing is disclosed. The composition includes poly(vinyl chloride), chlorinated poly(vinyl chloride), molybdenum oxide, alumina trihydrate, and isodecyl diphenyl phosphate as its primary ingredients, and additionally includes at least one heat stabilizer, at least one antioxidant, at least one lubricant, and at least one plasticizer besides the isodecyl diphenyl phosphate. It may also include antimony oxide, fillers, and chlorinated paraffins. The composition has excellent flame retardancy and produces only a relatively small amount of light-colored smoke when burned. |
