Insufficient PVA tensile strength
Sorun Belirtisi
PVA product tensile strength 15-20% below the standard value
Neden Analizi
PVA molecular weight on the low side, insufficient strength base; poor filler interface, no reinforcement effect; excessive orientation, strong longitudinally and weak transversely
Çözüm
1) Select high molecular weight PVA grade; 2) Treat filler with coupling agent to improve the interface; 3) Reduce orientation to reduce the longitudinal-transverse difference
Temel Çıkarım
Insufficient tensile strength is caused by molecular weight and poor interface; selecting a high MW grade is the key
