Thermoplastic Elastomer Composition Having Anti-Abrasion and Excellent Slip Property

摘要

PURPOSE: Provided is a thermoplastic elastomer composition for producing product under extrusion or drawing process having excellent abrasion-resistance and slip property comprising EPDM rubber together with styrene-ethylene-butadiene copolymer. CONSTITUTION: The composition comprises 50-100 parts by weight of EPDM rubber, 300-500 parts by weight of homo polypropylene, 10-40 parts by weight of filler, 1-10 parts by weight of styrene-ethylene-butadiene copolymer, 5-20 parts by weight of aliphatic amide, 2-10 parts by weight of cross-linking agent and 1-6 parts by weight of cross-linkage activating agent. EPDM rubber is three-member copolymer comprising ethylene and propylene as main components. The homo polypropylene has isotacticity of at least 96 and melt index (230deg.C, 2.16kg) ranging from 2-25g/min.
