Optimization of the Application of PPA in LLDPE film
Fenómeno del problema
Problems such as unstable effect occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the LLDPE film section.

The fluorine-to-carbon ratio of the PPA fluoropolymer does not match the base resin; the addition amount 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 full dispersion and coating formation.
