Large fluctuation of PU impact strength
Sorun Belirtisi
PU product impact strength fluctuates ±30%, unstable
Neden Analizi
PU dispersed phase particle size fluctuates 0.2-1μm, causing unstable toughening effect; crystallinity fluctuation affects impact
Çözüm
1) Stabilize processing conditions to ensure consistent dispersed phase particle size; 2) Nucleating agent to control crystallinity; 3) Raw material batch consistency control
Temel Çıkarım
Impact fluctuation is caused by unstable dispersed phase and crystallization; stable processing is key
