Abstract
Disclosed is a thermoplastic elastomer composition comprising 100 parts by weight of EPDM rubber, 5-1,000 parts by weight of styrenic thermoplastic elastomer, 50-3,000 parts by weight of paraffin oil, 10-200 parts by weight of a polyolefin resin as a curative, 1-15 parts by weight of a phenolic resin, and 0.5-5 parts by weight of a curing activator. The composition is superior in flowability, mechanical properties and oil resistance as well as being low in hardness, so that it can be applied for automobile parts.
