Title:
THERMOPLASTIC ELASTOMER COMPOSITION FOR DAMPING MEMBER
Document Type and Number:
WIPO Patent Application WO/2020/235006
Kind Code:
A1
Abstract:
An elastomer composition for a damping member that has an A hardness of 50 or less and includes a hydrogenated thermoplastic styrene elastomer A, which is a hydrogenation product of a block copolymer composed of a styrene polymer block (S1) and a conjugated diene compound polymer block (B1) with the 1,2-vinyl bond amount of the conjugated diene compound polymer block (B1) being 50% by mass or more, and a hydrogenated thermoplastic styrene elastomer B, which is a hydrogenation product of a block copolymer composed of a styrene polymer block (S2) and a conjugated diene compound polymer block (B2) with the 1,2-vinyl bond amount of the conjugated diene compound polymer block (B2) being less than 50% by mass, the [(hydrogenated thermoplastic styrene elastomer A)/(hydrogenated thermoplastic styrene elastomer B)] mass ratio being 5/95 to 55/45, a damping member and a rotor for an electric motor that are produced with the thermoplastic elastomer composition. The thermoplastic elastomer composition for a damping member of the present invention can be used for a damping member suitable against noise/vibration in home electric appliances, automobile parts, sports equipment, etc.
