Internal delamination cracking of PU
Sorun Belirtisi
Internal delamination of PU products, cracking along the interface
Neden Analizi
Poor interfacial bonding between PU and incompatible fillers or blend components; cooling shrinkage difference causing interlayer stress
Çözüm
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the addition amount of incompatible components
Temel Çıkarım
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
