Optimization of the Application of PPA in profile
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 profile section.
Análisis de la causa
The molecular weight 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 mixing and dispersion process.
Conclusión clave
The performance of PPA depends on synergy with the lubricant.
