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