PVA internal delamination cracking
Problembeschreibung
PVA product interior delaminates and cracks along the interface
Ursachenanalyse
Poor interfacial bonding between PVA and incompatible filler or blend components; cooling shrinkage differences cause interlayer stress
Lösung
1) Use compatibilizer to improve interfacial bonding; 2) Uniform cooling to reduce interlayer stress; 3) Reduce the amount of incompatible components added
Wichtigste Erkenntnis
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are the key
