Abstract
The invention provides an olefinic thermoplastic elastomer composition which is excellent in flexibility, processability into sheet and appearance of the resulting sheet and which is able to substitute for flexible polyvinyl chloride. The invention further provides a covering material for industrial parts comprising said composition and a laminate comprising said covering material. The composition comprises a partially crosslinked thermoplastic elastomer I containing an oil-extended olefinic copolymer rubber comprising an olefinic copolymer rubber having a Mooney viscosity of 200-350 or the thermoplastic elastomer I and a partially crosslinked thermoplastic elastomer II containing an oil-extended olefinic copolymer rubber comprising an olefinic copolymer rubber having a Mooney viscosity of 120 or higher and lower than 200 and the composition has a specific viscoelastic characteristics.
