THERMOPLASTIC ELASTOMER RESIN COMPOSITION AND VIBRATION-ABSORBING OBJECT COMPRISING SAME

摘要

A thermoplastic elastomer resin composition which comprises 50-95 parts by mass of a polyester-based thermoplastic elastomer (a) and 50-5 parts by mass of a styrene-based thermoplastic elastomer (b), characterized in that the thermoplastic elastomer resin composition has a glass transition temperature as measured with a dynamic viscoelastometer of 0-30ºC and has a tand at 23ºC of 0.22-0.40. The thermoplastic elastomer resin composition not only retains basic properties required of thermoplastic elastomer resin compositions, such as mechanical strength, moldability, and appearance, but also has low resilience and is free from bleeding of an additive.
