Optimization of the Application of PPA in color masterbatch
Problem Phenomenon
Problems such as uneven dispersion occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the color masterbatch section.
Cause Analysis
The particle size distribution of the PPA fluoropolymer does not match the base resin; the addition amount 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.
