Optimization of the Application of PPA in cable compound
Problem Phenomenon
Problems such as excessively high addition amount occurred with the PPA fluoropolymer processing aid in the process of reducing extrusion pressure in the cable compound section.
Cause Analysis
The particle size distribution of the PPA fluoropolymer does not match the base resin; the mixing process requires targeted optimization.
Solution
It is recommended to systematically adjust from aspects such as the addition method.
Key Takeaway
The performance of PPA depends on molecular design and matching with the base resin.
