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.
