Regulation of melt fracture of PPA in wire drawing Processing
Problem Phenomenon
The melt fracture abnormality of the PPA processing aid in wire drawing production affects efficiency.
Cause Analysis
The melt fracture of the PPA fluoropolymer is unsatisfactory at an addition amount of 0.05%, and the molecular weight needs to be optimized.
Solution
Adjust the PPA pretreatment process combined with screw design.
Key Takeaway
The key to the performance of PPA lies in coating formation.
