ABSTRACT:
The thermoplastic elastomer composition of the invention comprises a crystalline polyolefin resin (A), an olefin rubber (B), a hydrogenated styrene block copolymer (C), a softener (D), and optionally, a peroxide non-crosslinked type hydrocarbon rubber (E) in a specific amount of each, and has a gel content of not less than 97%. This composition may be mixed with a crystalline polyolefin resin. The thermoplastic elastomer composition has excellent moldability and is able to provide a molded product having excellent elastomeric properties, high resistance to permanent compression set and good appearance. In particular, a composition obtained by mixing this thermoplastic elastomer composition and a crystalline polyolefin resin shows excellent moldability.
