DSTDP internal delamination cracking
Fenómeno del problema
DSTDP product interior delaminates, cracking along the interface
Análisis de la causa
DSTDP has poor interfacial bonding with incompatible filler or blend components; cooling shrinkage differences cause interlayer stress
Solución
1) Use compatibilizer to improve interfacial bonding; 2) uniform cooling to reduce interlayer stress; 3) reduce the addition amount of incompatible components
Conclusión clave
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
