EVA elongation at break is low
문제 현상
EVA product elongation at break <100%, below the 200% requirement
원인 분석
EVA molecular weight too low with short chains and insufficient entanglement; excessive orientation with extremely low transverse elongation; excessive crosslinking restricting chain slippage
해결 방법
1) Select high molecular weight EVA to increase entanglement density; 2) Reduce orientation by lowering injection speed; 3) Control crosslinking degree to avoid excess
핵심 요약
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
