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