EVA hardness is too high
문제 현상
EVA product Shore hardness is 5-10 degrees higher than target, feels hard
원인 분석
EVA crystallinity too high with increased rigidity; too much filler added; cooling too fast with imperfect crystallization but rigidity frozen in
해결 방법
1) Reduce cooling rate to make crystallization complete and reduce the hard feel; 2) Reduce filler addition amount; 3) Add 0.5wt% plasticizer to reduce hardness
핵심 요약
High hardness is caused by crystallization and filler; adjusting cooling and filler is key
