Patent ID: 11492469

Abstract:
A thermoplastic elastomer composition including (A) ethylene rubber by 10 to 90 wt %, and (B) propylene polymer by 10 to 90 wt %, where a total amount of the thermoplastic elastomer composition is 100 wt %, is provided. A pressed sheet obtained by press-molding the thermoplastic elastomer composition under molding conditions has a sink-in temperature of 115° C. or higher. The sink-in temperature is measured based on JIS K7196-1991 as a temperature measured when a pressure load sinks in from a sheet surface by 100 μm. The molding conditions are such that the thermoplastic elastomer composition is hot press molded at a temperature of 200° C. with a maximum pressure of 10 MPa for 5 min, and thereafter cold press molded at a temperature of 23° C. with a maximum pressure of 10 MPa for 5 min, so as to prepare the pressed sheet.
