Regulation of fluorine content selection of PPA in BOPP Processing
Problem Phenomenon
The fluorine content selection abnormality of the PPA processing aid in BOPP production affects quality.
Cause Analysis
The fluorine content selection 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.
