POE internal delamination cracking
Fenómeno do problema
POE product internal delamination, cracking along the interface
Análise das causas
POE and incompatible filler or blend component interfacial adhesion poor; cooling shrinkage difference causes interlayer stress
Solução
1) Use compatibilizer to improve interfacial adhesion; 2) Uniform cooling to reduce interlayer stress; 3) Reduce incompatible component addition
Conclusão principal
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
