Internal delamination cracking of PU
ظاهرة المشكلة
Internal delamination of PU products, cracking along the interface
تحليل الأسباب
Poor interfacial bonding between PU and incompatible fillers or blend components; cooling shrinkage difference causing interlayer stress
الحل
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the addition amount of incompatible components
الخلاصة الأساسية
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
