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