Abstract

열가소성 폴리우레탄 및 폴리우레판을 기준으로 하여 0.3 내지 15ppm(주석 원자로 환산)양의 주석 화합물을 포함하는 열가소성 폴리우레탄 조성물. 조성물을 220℃에서 60분 동안 용융가열하는 경우, 폴리우레탄의 장쇄하드 세그먼트의 보유율은 85%이상이다. 또한, 조성물을 220℃에서 6분 동안 용융 처리하고 용융압출시킨 다음 20℃ 및 60%의 상대 습도에서 24시간 동안 방치시킨 경우 대수 점도의 보유율은 85% 이상이다.
조성물은 성형성이 우수하여 각종 특성(예:인장강도 및 신도, 내열성, 압축 영구왜곡 및 내가수분해성)이 우수한 성형품을 제공할 수 있으므로, 각종 성형품의 재료로서 유용하다. 또한, 방사성이 우수하여 각종 특성(예:내열성, 내가수분해성 및 해사성)이 우수한 섬유를 제공할 수 있으므로, 탄성 섬유의 재료로서도 또한 유용하다.
