EVA toughness is insufficient with brittle fracture
문제 현상
EVA product elongation at break <50%, brittle fracture without yielding
원인 분석
EVA molecular weight too low with insufficient toughness foundation; excessive crosslinking losing toughness; coarse crystallization increasing brittleness
해결 방법
1) Select high molecular weight EVA to improve toughness; 2) Control crosslinking degree to avoid excess; 3) Nucleating agent to refine crystallization and improve toughness
핵심 요약
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is key
