Thermoplastic elastomer composition. |
摘要 |
<p>A thermoplastic elastomer composition comprising (A) 10-90 parts by weight of crystalline polypropylene, (B) 10-90 parts by weight of brominated butyl rubber, (C) 10-120 parts by weight of olefinic copolymer rubber to 100 parts by weight of (A) + (B), and (D) 10-150 parts by weight of process oil as plasticizer to 100 parts by weight (A) + (B), all of which are dynamically vulcanized in the presence of a peroxide crosslinking agent. The thermoplastic elastomer composition of this invention has a high gel ratio or gel content in part because brominated butyl rubber is vulcanized with peroxide. The composition has good elasticity, high mechanical strength, low compressively permanent set, excellent long-term heat stability, moldability, and gas impermeability and high damping characteristic.</p> |
