Abstract

성형품의 손의 감촉 느낌에 있어서, 소프트감을 증대시키는 것이 용이하게 됨과 함께, 코어층 및 표피층의 경시적인 물성변화가 촉진되지 않는 에어백 장치용 패드를 제공하는 것.
자동차의 스티어링 휠등에 장착되는 에어백 장치의 윗면을 덮는 패드(5), 이 패드(5)는, 연직의 제1수지재료로 형성되어지는 표피층(1)과, 제1수지재료로부터 경질의 제2수지 재료로 형성되어지는 코어층(3)으로 형성된다.
제1수지 재료가, 경도(JIS A)70이하의 스틸렌계 열가소성 에라스토머(TPE) 또는 오레핀계 TPE 이며, 제2수지 재료가, 구부림 탄성율1000 내지 4000kgf/㎤(98 내지 392MPa)의 폴리에스테르계 TPE 이다.
