THERMOPLASTIC ELASTOMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/060201
Kind Code:
A1
Abstract:
[Problem] To provide a thermoplastic elastomer composition having excellent heat resistance, fluidability, blushing resistance, surface properties, mechanical properties and thin film formability.
[Solution] The problem can be solved by a thermoplastic elastomer composition comprising: 100 parts by mass of a hydrogenated block copolymer (A) which is produced by the hydrogenation of a block copolymer that comprises a polymer block (a) comprising an aromatic vinyl compound and a polymer block (b) comprising a conjugated diene compound, and which has a solution viscosity falling within the range from 50 to 200 mPa·s as measured in a 5 mass% toluene solution at 30°C; 150 to 350 parts by mass of a softening agent for hydrocarbon-type rubbers (B); 150 to 350 parts by mass of an olefin resin (C) which comprises a propylene-type polymer and an ethylene-type polymer, wherein the content of the ethylene-type polymer is 1 to 20% by mass; and 0.05 to 3 parts by mass of a silicone oil (D) which has a kinematic viscosity of 200 mm2/s or less as measured at 25°C.
