PTFE for Greases and Lubricants
Natural Prime PTFE
Fluoro GE sub-micron PTFE are powders made from emulsion grade Natural Prime PTFE. These products cover a range of molecular weights to determine dispersability, thickening and performance properties. Due to the small particle size, the GE products have a larger specific surface area when compared to other PTFE.
