PVA internal delamination cracking
문제 현상
PVA product interior delaminates and cracks along the interface
원인 분석
Poor interfacial bonding between PVA and incompatible filler or blend components; cooling shrinkage differences cause interlayer stress
해결 방법
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the amount of incompatible components added
핵심 요약
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are the key
