Optimization of the Application of PPA in pipe coating
Problembeschreibung
Problems such as excessively high addition amount occurred with the PPA fluoropolymer processing aid in the process of eliminating melt fracture in the pipe coating section.
Ursachenanalyse
The particle size distribution of the PPA fluoropolymer does not match the base resin; the screw configuration requires targeted optimization.
Lösung
It is recommended to systematically adjust from aspects such as the addition method.
Wichtigste Erkenntnis
The performance of PPA depends on molecular design and matching with the base resin.
