Insufficient EMA transparency

Sorun Belirtisi

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

Neden Analizi

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

Çözüm

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

Temel Çıkarım

EMA transparency is affected by MMA content and crystallization scattering
