3M™ Dynamar™ Polymer Processing Additive FX 5911
Dynamar FX 5911 improves extrusion processing of polyolefins and other thermoplastic resins, and can offer performance and cost benefits in a wide range of polymers. It is particularly useful at low levels in reducing extruder die build-up. Dynamar FX 5911 lowers apparent melt viscosity and permits fabricators to use high viscosity, high molecular weight resins in many film, pipe and blow molding processes 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 improved surface finish and quality. As a polymer processing additive (PPA), Dynamar FX 5911 reduces or eliminates melt fracture and can reduce extruder torque. Through optimization of the extrusion process, the use of Dynamar FX 5911 may also allow for an increase in output during extrusion. Dynamar FX 5911 is effective at low use levels in reducing die build-up in many polymers including LLDPE, LDPE, HDPE, PP and other thermoplastic resins. This allows for longer defect-free run times and improved gauge uniformity in cast film (see Figures 1 and 2) and BOPP processes as well as reduced fiber breakage in monofilament and fiber processes.
