3M™ Dyneon™ PTFE Micropowder TF 9201Z is a non-degraded, low molecular weight virgin PTFE suitable for use in food contact applications. TF 9201Z is used as an additive to improve non-stick properties, to reduce the coefficient of friction and to increase wear resistance of matrix materials.
Distinctive features of TF 9201Z include:
agglomerated particles
easily deagglomerated when incorporated into other matrixes
FDA compliant up to 20 percent by weight in polymer formulations

3M™ Dyneon™ PTFE Micropowder TF 9201Z can be used as an additive in
polymer applications at concentrations typically from 5 to 20 percent.
Plastics
that can benefit from improved lubricity and reduced friction and wear
include polyacetals, polyamides, polycarbonates, polyesters, polyimides,
polysulphides and polysulphones. Elastomers that can benefit include
fluoroelastomers, neoprenes, nitriles and silicones.
Homogeneous
incorporation is the single most important process and application
consideration. Because of its small particle size coupled with good
free-flowing properties, TF 9201Z exhibits very good metering behaviour
and can be easily incorporated into materials – even in dry blends. For
optimum handling it is recommended that the micropowder and matrix
material both be at a temperature below 30 °C (86 °F). In the case of
thermoplastic blends, however, the micropowder may be metered directly
into the melt. High speed mixers and tumble mixers have proven
successful for dry blends, while propeller mixers work well for wet
mixtures such as solvents and oils. Glass bead mills should be used for
relatively high viscosity mixtures and roll mills for very high
viscosity applications, such as lubricating greases and oils.
