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