Optimization of the Application of PPA in pipe coating
Fenómeno del 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.
Análisis de la causa
The particle size distribution of the PPA fluoropolymer does not match the base resin; the screw configuration requires targeted optimization.
Solución
It is recommended to systematically adjust from aspects such as the addition method.
Conclusión clave
The performance of PPA depends on molecular design and matching with the base resin.
