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