Daikin fluoro based polymers processing aids are additives used to increase productivity and quality of PE materials during extrusion. These additives have the advantage to not compromise on PE performance as only few hundred ppm are needed.

How does Daikin’s Polymer Processing Aids work?

During extrusion process of polyolefin such as PE films, tubes or pipes, the melted polymers flow with a higher speed in the middle of the gap than on the sides. At the exit of the extruder, this difference causes irreversible damages, such as melt fracture, die build up and polymer degradation resulting in gels and black spots (see figure below).

Small amount of polymer processing aids (PPA) incorporated in the formulation can eliminate all these problems. Thanks to the affinity from fluoropolymers with metal, they migrate to the surface, constituting thin layer on the walls. The polymer slips in the extruder, at uniform speed. The melt fracture and all other side effects disappear. Black specks can also be purged out.

As no polymer processing aids remain on the surface of the extruded PE films, all your PE tubes, pipes can be easily printed or sealed.
