EVOH Internal Delamination Cracking

문제 현상

EVOH products delaminate internally, cracking along the interface

원인 분석

Poor interfacial adhesion between EVOH and incompatible fillers or blend components; cooling shrinkage differences causing interlayer stress

해결 방법

1) Use compatibilizer to improve interfacial adhesion; 2) Uniform cooling to reduce interlayer stress; 3) Reduce addition of incompatible components

핵심 요약

Internal delamination is caused by poor interface and shrinkage differences; compatibilizer and uniform cooling are key
