This theraoplast Ic I* based on bland of PVC and Hycar, and contains antimony trioxide flame retardant. ************ We analysed Uniroyal TPR-3700 as follows: Polyoar Plasticizer Carbon black Antimony trloxide $0 percent 35-M) 5-10 " 5 The polyaer Is a alxture of polyvinyl ehlorlda and a butadlene/acrylonitrl1e copolyaar (Hycar). Thera eppoars to be about 70 percent PVC in the alxture. The copolymer has 30 to 35 percent acrylonitrIle. The plasticizer Is a non-aromatlc potyaarlc polyester type with a spectrun fairly slallar to the spectrua of Hallco's HA-5-A plasticizer. The XRF quaI scan (filenelos) data, normal I zed to Cl (highest concentration) ware: C! Sb $n Pb Ce.K.S re Zn highest very high moderate low to moderate low very low uncertain This suggests that alxture of tin aercaptlde and lead compounds are present as PVC stabilizers.
