Insufficient EMA transparency

문제 현상

EMA film haze >20%, below the 5% transparent packaging requirement

원인 분석

EMA methyl methacrylate content too low with crystalline region scattering; extrusion cooling rate too fast

해결 방법

1) High MMA content EMA with MMA>20% to lower crystallinity; 2) Lower cooling rate; 3) 0.3wt% nucleating agent for uniform crystallization

핵심 요약

EMA transparency is affected by MMA content and crystallization scattering

EMA film transparency haze MMA content nucleating agent
