EEA Large Compression Set
ظاهرة المشكلة
EEA product compression set >30%, lower than the 15% requirement
تحليل الأسباب
EEA elastic recovery insufficient; crosslinking degree low, plastic deformation unrecoverable; density low, cell walls thin, recovery poor
الحل
1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high-elastic-recovery EEA grades; 3) Add reinforcing fillers
الخلاصة الأساسية
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
