POE toughened PP directionality obvious
Sorun Belirtisi
POE/PP longitudinal-transverse impact difference 2 times
Neden Analizi
POE dispersed phase is stretched and oriented into long strips during injection instead of spheres
Çözüm
1) Lower injection speed to reduce orientation; 2) Mold temperature 50-60°C; 3) Multi-point gates to reduce unidirectional flow; 4) Nucleating agent to refine grains
Temel Çıkarım
Directionality difference is caused by POE orientation; reducing speed and multi-point gates are key
