Optimization of the Application of PPA in HDPE pipe
Fenómeno del problema
Problems such as unstable effect occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the HDPE pipe section.
Análisis de la causa
The fluorine-to-carbon ratio of the PPA fluoropolymer does not match the base resin; the processing temperature 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.
