Delivering comparable processing performance to traditional processing aids, Avient’s Cesa Non-PFAS Process Aid reduces friction between the polymer and the metal, allowing the polymer to be more easily extruded. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

Avient’s new Cesa Non-PFAS Process Aid delivers performance characteristics similar to traditional fluoropolymer-based options, reducing friction between the polymer and the metal, allowing the polymer to be more easily extruded. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

Similar to prime density modified grades, these new materials can be extruded, molded, calendered, or thermoformed into complex designs without expensive tooling. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

It works by injecting liquid color at high pressure into the polymer melt- flow between the end of the extruder, or melt-pipe, and the spin head. The extruder is never contaminated with color which translates into faster, more efficient color changeovers that make low volume and custom color production a reality.

A compounding extruder connected to the impregnation die functions as a melt pump feeding molten thermoplastic polymer into the process. 

Precautions: the extruder should not be idle with the material in the barrel, bleed constantly when possible.
