EEA Low Elongation at Break
ظاهرة المشكلة
EEA product elongation at break <100%, below the 200% requirement
تحليل الأسباب
EEA molecular weight low, chains short, entanglement insufficient; excessive orientation, transverse elongation extremely low; excessive crosslinking limits chain slippage
الحل
1) Select high-molecular-weight EEA 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
