POE compression set large
문제 현상
POE product compression set >30%, below 15% requirement
원인 분석
POE elastic recovery insufficient; crosslinking degree low, plastic deformation unrecoverable; density low, cell walls thin, recovery poor
해결 방법
1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high elastic recovery POE grade; 3) Add reinforcing filler
핵심 요약
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
