PTFE is an abbreviation for polytetrafluoroethene which is a polymer made from the monomer tetrafluoroethene (CF2CF2). It is a thermosetting plastic with a high melting point that is used to produce ‘non-stick’ surfaces on pans and to coat bearings amongst other things.
PTFE greases are high performance, specialist greases with PTFE solids.
They are highly specialised and have:
Good compatibility with plastics and elastomers
Effective usage on metal-metal applications and metal-plastic
