Processing difficulty after adding thermally conductive fillers to PET
Fenómeno del problema
After adding thermally conductive fillers (graphite, boron nitride) to PET, melt viscosity increases sharply, processing difficult, surface rough.
Análisis de la causa
High filling amount (>30%) causes sharp fluidity decline, poor filler-matrix compatibility produces interfacial friction, uneven filler dispersion.
Solución
Use coupling agents to improve the interface; optimize screw configuration to improve dispersion; appropriately increase processing temperature; control filling amount ≤50%.
Conclusión clave
PET thermally conductive composite processability depends on filler selection and interface treatment.
