Low EVOH Elongation at Break
ظاهرة المشكلة
EVOH product elongation at break <100%, below the 200% requirement
تحليل الأسباب
EVOH molecular weight too low, chains short with insufficient entanglement; orientation excessive, transverse elongation extremely low; crosslinking excessive restricting chain slippage
الحل
1) Select high molecular weight EVOH to increase entanglement density; 2) Reduce orientation by lowering injection speed; 3) Control crosslinking degree to avoid excess
الخلاصة الأساسية
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
