Internal delamination cracking of PU
문제 현상
Internal delamination of PU products, cracking along the interface
원인 분석
Poor interfacial bonding between PU and incompatible fillers or blend components; cooling shrinkage difference causing interlayer stress
해결 방법
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the addition amount of incompatible components
핵심 요약
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
