A thermoplastic elastomer composition comprising (A) 50-98% by weight of a thermoplastic polyester elastomer, (B) 50-2% by weight of a rubber and (C) a polyorganosiloxane in a proportion of 0.01-10 parts by weight per 100 parts of the total of the components (A) and (B). The above thermoplastic elastomer composition enables one to improve the flexibility and compression set of the thermoplastic polyester elastomer excellent in mechanical properties, heat resistance and oil resistance without impairing the abrasion resistance of the thermoplastic polyester elastomer. |
