Optimization of the Application of PPA in HDPE pipe
Fenómeno do 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.
Análise das causas
The fluorine-to-carbon ratio of the PPA fluoropolymer does not match the base resin; the processing temperature 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.
