EVA foam cells are uneven

문제 현상

EVA foamed sheet cells 50-500μm, uneven in size

원인 분석

AC blowing agent unevenly dispersed, dry powder directly added; uneven melt viscosity

해결 방법

1) Blowing agent masterbatch method; 2) Fully mix EVA; 3) Crosslinking agent masterbatch method; 4) Mold ±2°C

핵심 요약

Cell uniformity depends on blowing agent dispersion and crosslinking uniformity

EVA foam uneven cells blowing agent masterbatch crosslinking uniformity mold temperature control
