Regulation of melt fracture of PPA in foaming Processing
Problem Phenomenon
The melt fracture abnormality of the PPA processing aid in foaming production affects output.
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 addition amount combined with formulation adjustment.
Key Takeaway
The key to the performance of PPA lies in uniform dispersion.
