What is PFAS-FREE PPA?

FlexDasin DS series products are PFAS-free polymer processing additive (PPA) developed by Daken Chemical.

PFAS-FREE PPA From Daken Chemical Limited

Production Introduction of Daken PFAS-FREE PPA

Daken PFAS-FREE PPA is an organo-modified polysiloxane product designed for use at a low level to improve the processing of plastics. With the excellent initial lubrication effect of polysiloxane and the polarity of the modified group, Daken PFAS-FREE PPA can migrate to the processing equipment during processing and produce effects as a polymer processing aid(PPA).

At the low use levels necessary to improve processing, it does not alter or detract from the mechanical properties associated with high strength plastics. As a polymer processing additive (PPA), Daken PFAS-FREE PPA can effectively improve the resin fluidity, additivity, lubricity and surface properties during plastic extrusion.

It can also reduce or eliminate melt fracture, improve wear resistance, reduce friction coefficient, extend equipment cleaning cycle, shorten downtime. Through optimization of the extrusion process, the use of Daken PFAS-FREE PPA may also allow an increase in output and a better products surface. Daken PFAS-FREE PPA is a perfect choice to replace fluoride-based PPA, especially in terms of safety and environmental protection.

Application of Daken PFAS-FREE PPA

Daken PFAS-FREE PPA can help manufacturers improve the quality and output of a variety of extruded products. Daken PFAS-FREE PPA works by forming a low surface energy coating on the die surface, which allows the melt to slide through the die more freely and easily without sticking. Daken PFAS-FREE PPA has been widely used in blown and cast film processes, pipe and sheet extrusion, cable, fiber and monofilament extrusion, blow molding and compounding. It is effective at low usage levels, so just a small amount can reduce common processing issues, such as die buildup and melt fracture. The use of Daken PFAS-FREE PPA improves surface quality, reduces waste, increases productivity, and makes the extrusion process smoother from start to finish.
