Optimization of the Application of PPA in wire drawing
Problem Phenomenon
Problems such as excessively high addition amount occurred with the PPA fluoropolymer processing aid in the process of improving surface quality in the wire drawing section.
Cause Analysis
The molecular weight 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 PPA molecular structure design.
Key Takeaway
The performance of PPA depends on molecular design and matching with the base resin.
