Application optimization of PPA in PP extrusion
Problembeschreibung
During the process of improving surface quality in the PP extrusion section, the PPA fluoropolymer processing aid shows problems such as uneven dispersion.
Ursachenanalyse
The molecular weight of the PPA fluoropolymer does not match the base resin; the screw configuration needs targeted optimization.
Lösung
It is recommended to make systematic adjustments in aspects such as PPA molecular structure design.
Wichtigste Erkenntnis
The performance of PPA depends on the matching between molecular design and the matrix.
