EMA internal delamination cracking

Problembeschreibung

EMA products delaminate internally, cracking along interfaces

Ursachenanalyse

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

Lösung

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

Wichtigste Erkenntnis

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