Coarse internal crystallization of EAA
문제 현상
The spherulites inside EAA products are coarse >50μm, causing reduced transparency and low impact
원인 분석
Cooling rate too slow <5°C/min allows spherulites to fully grow; no nucleating agent used to control crystallization
해결 방법
1) Increase the cooling rate to >20°C/min to refine spherulites; 2) Add 0.2-0.3wt% nucleating agent to control crystallization; 3) Lower the mold temperature to accelerate cooling
핵심 요약
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are the key
