EVA foam surface large bubbles
Sorun Belirtisi
EVA foam large bubbles >2mm
Neden Analizi
AC locally agglomerated with decomposed large amounts of gas concentrated; foaming temperature too high with local overheating
Çözüm
1) AC masterbatch method to ensure dispersion without agglomeration; 2) Temperature ±2°C; 3) DCP masterbatch method for uniform crosslinking
Temel Çıkarım
Large bubbles are caused by blowing agent agglomeration and uneven temperature; masterbatch method is key
