POE internal delamination cracking
Problembeschreibung
POE product internal delamination, cracking along the interface
Ursachenanalyse
POE and incompatible filler or blend component interfacial adhesion poor; cooling shrinkage difference causes interlayer stress
Lösung
1) Use compatibilizer to improve interfacial adhesion; 2) Uniform cooling to reduce interlayer stress; 3) Reduce incompatible component addition
Wichtigste Erkenntnis
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
