  • Thermoplastic elastomer and manufacturing method thereof
    Publication number: 20060084740
    Abstract: A low-smoke, halogen-free and flame-retardant thermoplastic elastomer is provided in the present invention. The thermoplastic elastomer includes a polymer having a hydrogenated styrenic/conjugated diene copolymer, an inorganic phosphorus flame-retardant and a flame-retardant auxiliary, wherein a weight of the hydrogenated styrenic/conjugated diene copolymer is 50-100 percents of a weight of the polymer, a weight of the inorganic phosphorus flame-retardant is ranged from 0.3 to 2 times of the weight of the hydrogenated styrenic/conjugated diene copolymer, and a weight of the flame-retardant auxiliary is ranged from 0.05 to 0.4 times of the weight of the hydrogenated styrenic/conjugated diene copolymer.
