Coarse internal crystallization of EMA
Sorun Belirtisi
Coarse spherulites >50μm inside EMA products cause reduced transparency and low impact strength
Neden Analizi
Cooling rate too slow <5°C/min allows spherulites to grow fully; no nucleating agent used to control crystallization
Çözüm
1) Increase cooling rate to >20°C/min to refine spherulites; 2) Add 0.2-0.3wt% nucleating agent to control crystallization; 3) Lower mold temperature to accelerate cooling
Temel Çıkarım
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are key
