CEF toughness insufficient brittle fracture
Fenómeno del problema
The elongation at break of the CEF product is <50%, brittle fracture without yielding
Análisis de la causa
The CEF molecular weight is low and the toughness foundation is insufficient; excessive crosslinking loses toughness; coarse crystallization increases brittleness
Solución
1) Select high-molecular-weight CEF to improve toughness; 2) Control the crosslinking degree to avoid excessiveness; 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 the key
