EEA Low Elongation at Break

Fenómeno del problema
EEA product elongation at break <100%, below the 200% requirement
Análisis de la causa
EEA molecular weight low, chains short, entanglement insufficient; excessive orientation, transverse elongation extremely low; excessive crosslinking limits chain slippage
Solución
1) Select high-molecular-weight EEA to increase entanglement density; 2) Reduce orientation by lowering injection speed; 3) Control crosslinking degree to avoid excess
Conclusión clave
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
EEA elongation at break molecular weight orientation control crosslinking degree
