Polytetrafluoroethylene, also known as PTFE or Teflon®, is a chemically inert fluoropolymer with the lowest coefficient of friction of any solid. The unique structure of PTFE molecules also gives this material excellent hydrophobic qualities and the ability to repel dust, dirt, and grime that would stick to oil-based lubricants. PTFE powder may be compounded or tumbled with a variety of materials for anti-stick applications or blended with liquid dispersants to create a mold release agent or dry film lubricant.

Applications
Uses
Blending with Polymers, Elastomers, and Composites
Compounded in to provide inherent anti-sticking properties and improved abrasion resistance. Will not interfere with material integration, curing, or vulcanization.
Blending with Paints and Inks
Compounded in to improve slip properties and abrasion resistance. Can be used with epoxy, acrylics, urethanes, printing inks, sealants, and variety of waxes.
Tumbling
PTFE powder may be tumbled with tacky polymeric or elastomeric materials to prevent sticking and repel water and other contaminants. Powdered PTFE may also be “thumbed” onto parts to aid assembly and insertion.
Dispersions
PTFE powder may be blended in water, solvents, oils, or greases for more effective delivery of PTFE’s low coefficient of friction to the substrate.
