EVA foam density is too high
Sorun Belirtisi
EVA foamed shoe material density 0.35 is higher than 0.25g/cm³
Neden Analizi
Insufficient AC or incomplete decomposition; VA<15% high viscosity suppresses expansion; insufficient crosslinking
Çözüm
1) AC 0.8-1.2wt%; 2) VA18-28% to reduce viscosity and promote expansion; 3) Foaming at 170-180°C; 4) DCP 0.4-0.6wt% to stabilize cells
Temel Çıkarım
EVA foam density is determined by the blowing agent, VA content, and crosslinking degree
