Poor resilience of PU flexible foam

문제 현상

PU flexible foam resilience <40%, below 60%

원인 분석

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

해결 방법

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

핵심 요약

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

PU flexible foam resilience isocyanate index catalyst foam density
