Fluro Polymer Processing Aids PPA
Fluro Polymer Processing Aids (PPA)
Fluro PPA is made by fluro cooplymers to be an additive by creating a dynamic, temporary fluoropolymer coating on the die surface. The coating provides a low surface energy interface between the metal wall and the molten polymer stream. This reduces stress in the die, prevents drag and allows the melt to slip through the die more easily and without sticking- thereby eliminating melt fracture.
