EVA foam open cell content is high
Sorun Belirtisi
EVA foam open cells >30%, exceeding 10%
Neden Analizi
Foaming temperature too high with thin cell walls rupturing into open cells; insufficient crosslinking with low wall strength
Çözüm
1) Reduce temperature by 5-10°C to reduce wall rupture; 2) DCP 0.5-0.8wt% to increase wall strength; 3) Appropriately reduce AC to reduce gas pressure impact
Temel Çıkarım
High open cell content is caused by cell wall rupture; temperature control and moderate crosslinking are key
