摘要:
PURPOSE: A thermoplastic elastomer composition is provided to provide a molded product with low permanent stain, especially when cooled in a pressurized state.CONSTITUTION: A thermoplastic elastomer composition comprises a dynamically crosslinked butyl-based rubber and thermoplastic resin. The content of the thermoplastic resin is 8 wt% or less. The crosslinked butyl-based rubber is a halogen-containing butyl rubber. The dynamically crosslinked butyl-based rubber is manufactured by dynamically crosslinking 0.1-10 parts by weight of a triazine derivative to 100.0 parts by weight of the rubber component. The thermoplastic resin is an olefin resin. The composition additionally includes 0-100 parts by weight of a softener, based on 100.0 parts by weight of the dynamically crosslinked butyl-based rubber.COPYRIGHT KIPO 2013본 발명은, 압축 영구 변형율, 특히 가압한 채로 냉각된 경우의 압축 영구 변형율이 작은 성형품을 제공할 수 있는 동적 가교된 열가소성 엘라스토머 조성물을 제공하는 것을 목적으로 한다. 본 발명은, 동적 가교된 부틸계 고무 및 열가소성 수지를 포함하고, 열가소성 수지의 함량이 8 질량% 이하인 열가소성 엘라스토머 조성물에 관한 것이다. 동적 가교된 부틸계 고무가 할로겐 함유 부틸 고무인 것이 바람직하다.
