3M™ Dynamar™ Polymer Processing Additive FX 5911 is a free-flowing fluoropolymer processing aid that is designed for use at very low levels to improve processing of thermoplastics. At the very low use levels (typically 250 - 1000 ppm) necessary to improve processing, it does not alter or detract from the good physical properties associated with high strength plastics.

Dynamar FX 5911 can offer performance and cost benefits in a wide range of polyolefin resins. It is particularly useful at low levels in reducing extruder die build-up. FX 5911 also exhibits exceptional commercial utility in high viscosity, high molecular weight polyolefin resins.

FX 5911 lowers apparent melt viscosity and permits fabricators to use high viscosity, high molecular weight resins in many cast and blown film, and blow molding applications which otherwise could not be processed on available equipment. Now with the aid of FX 5911, fabricators can produce blow molded bottles, pipes and other HMW HDPE articles with excellent gloss values and improved quality.

As a processing aid FX 5911 reduces or eliminates melt fracture and can reduce extruder torque. Through optimization of the extrusion process, the use of FX 5911 may also allow an increase in output in other high molecular weight, high viscosity conversion processes. Because of its enhanced efficiency in reducing die build- up and its continued cleaning performance, equipment maintenance can be minimized.
