Application optimization of PPA in PP extrusion
Fenómeno del problema
During the process of improving surface quality in the PP extrusion section, the PPA fluoropolymer processing aid shows problems such as uneven dispersion.
Análisis de la causa
The molecular weight of the PPA fluoropolymer does not match the base resin; the screw configuration needs targeted optimization.
Solución
It is recommended to make systematic adjustments in aspects such as PPA molecular structure design.
Conclusión clave
The performance of PPA depends on the matching between molecular design and the matrix.
