Optimization of the Application of PPA in PVC profile
Fenómeno del problema
Problems such as uneven dispersion occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the PVC profile section.
Análisis de la causa
The molecular weight of the PPA fluoropolymer does not match the base resin; the mixing process requires targeted optimization.
Solución
It is recommended to systematically adjust from aspects such as the formulation synergy.
Conclusión clave
The performance of PPA depends on molecular design and matching with the base resin.
