ظاهرة المشكلة
EVA product internal delamination cracking along the interface
تحليل الأسباب
Poor interfacial adhesion between EVA and incompatible fillers or blend components; cooling shrinkage differences causing interlayer stress
الحل
1) Use compatibilizer to improve interfacial adhesion; 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 differences; compatibilizer and uniform cooling are key
