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