EEA Insufficient Toughness, Brittle Fracture
Fenómeno del problema
EEA product elongation at break <50%, brittle fracture without yielding
Análisis de la causa
EEA molecular weight low, toughness foundation insufficient; excessive crosslinking, toughness lost; coarse crystallization, brittleness increased
Solución
1) Select high-molecular-weight EEA to improve toughness; 2) Control crosslinking degree to avoid excess; 3) Nucleating agent to refine crystallization and improve toughness
Conclusión clave
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is key
