Poor resilience of PU flexible foam

Sorun Belirtisi

PU flexible foam resilience <40%, below 60%

Neden Analizi

Isocyanate index too high >1.1; foam density too high; improper catalyst formulation

Çözüm

1) Lower isocyanate index to 0.95-1.0; 2) Increase blowing agent to reduce density; 3) Adjust catalyst formulation

Temel Çıkarım

PU flexible foam resilience is determined by isocyanate index and catalyst formulation

PU flexible foam resilience isocyanate index catalyst foam density
