POE toughened PP stiffness-toughness balance poor
Fenómeno del problema
POE/PP flexural >800MPa and impact >10kJ/m², one item not up to standard
Análisis de la causa
Toughening and stiffening contradict; simple binary system cannot meet both standards simultaneously
Solución
1) POE+talc ternary; 2) Nucleating agent 0.2wt% balancing stiffness and toughness; 3) POE particle size 0.3-0.5μm; 4) POE-g-MAH to reduce POE dosage
Conclusión clave
Stiffness-toughness balance requires ternary system and optimized POE particle size
