Optimization of the Application of PPA in pipe coating
Fenómeno do problema
Problems such as excessively high addition amount occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the pipe coating section.
Análise das causas
The particle size distribution of the PPA fluoropolymer does not match the base resin; the screw configuration requires targeted optimization.
Solução
It is recommended to systematically adjust from aspects such as the addition method.
Conclusão principal
The performance of PPA depends on molecular design and matching with the base resin.
