Regulation of surface roughness of PPA in cable Processing
Problem Phenomenon
The surface roughness abnormality of the PPA processing aid in cable production affects quality.
Cause Analysis
The surface roughness of the PPA fluoropolymer is unsatisfactory at an addition amount of 0.08%, and the molecular weight needs to be optimized.
Solution
Adjust the PPA addition amount combined with screw design.
Key Takeaway
The key to the performance of PPA lies in matching with the base resin.
