Optimization of the Application of PPA in profile
Problem Phenomenon
Problems such as excessively high addition amount occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the profile section.
Cause Analysis
The molecular weight of the PPA fluoropolymer does not match the base resin; the processing temperature requires targeted optimization.
Solution
It is recommended to systematically adjust from aspects such as the mixing and dispersion process.
Key Takeaway
The performance of PPA depends on synergy with the lubricant.
