Abstract: The present invention provides a thermoplastic elastomer foaming product, comprising: (a) a hydrogenated styrenic/conjugated diene copolymer, (b) a polyolefin, (c) a plasticizer, and optional additives such as blowing agents, cross-linking agents, promoters, fillers, stabilizers and the like. The thermoplastic elastomer foaming product is soft in nature and has a low specific gravity. The present invention also provides a method of forming the above thermoplastic elastomer foaming product.

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.
