PTFE Powder Additive for Greases and Lubricants
Micronized polytetrafluoroethylene (PTFE) powder is used as a solid lubricant additive in greases and dry lubricants, reducing the coefficient of friction and improving wear resistance under light- to medium-load boundary lubrication conditions. PTFE particles deposit on metal surfaces to form a low-energy, low-friction transfer film. They are particularly effective in precision bearings, instrument mechanisms, and thread compounds where conventional lubricants would cause interference or contamination.
