EVA compression set is large
Sorun Belirtisi
EVA product compression set >30%, below the 15% requirement
Neden Analizi
EVA elastic recovery insufficient; crosslinking degree too low with unrecoverable plastic deformation; density too low with thin cell walls and poor recovery
Çözüm
1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select EVA grades with high elastic recovery; 3) Add reinforcing fillers
Temel Çıkarım
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
