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