Beschreibung
Zusammenfassung:	The present invention relates to a foam composition for a lightweight shoe midsole with high durability, and more particularly, to a foam composition for a lightweight shoe midsole with high durability, which is lightweight with hardness and specific gravity similar to ethylene-based foam, while further improving durability, such as permanent compression set and rebound elasticity, by manufacturing a foam for a shoe midsole using materials including EVA, styrene-based thermoplastic elastomer, high molecular weight styrene-based thermoplastic elastomer, and polyphenylene ether resin. 본 발명은 고내구성을 가지는 경량 신발 중창용 발포체 조성물에 관한 것으로, 보다 구체적으로는 EVA, 스티렌계 열가소성 탄성체, 고분자량 스티렌계 열가소성 탄성체 및 폴리페닐렌에테르계 수지로 이루어진 기재를 사용하여 신발 중창용 발포체를 제조함으로써, 에틸렌계 소재의 발포체와 유사한 경도 및 비중으로 경량성을 가지면서도 영구압축줄음율 및 반발탄성 등의 내구성을 더욱 향상시킬 수 있도록 하는, 고내구성을 가지는 경량 신발 중창용 발포체 조성물에 관한 것이다.
