MP internal coarse crystallization
문제 현상
MP products have internal spherulites >50μm, coarse, causing reduced transparency and low impact
원인 분석
cooling rate too slow <5°C/min, allowing spherulites to fully grow; no nucleating agent used to control crystallization
해결 방법
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
핵심 요약
coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are key
