EEA Large Compression Set

문제 현상

EEA product compression set >30%, lower than the 15% requirement

원인 분석

EEA 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 EEA grades; 3) Add reinforcing fillers

핵심 요약

Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
