Over seventy years ago a DuPont scientist, discovered polytetrafluoroethylene. (PTFE) — a fluoropolymer that is corrosive chemical and heat resistance, and the world’s most slippery surface. PTFE Coated Bolts have a Low Coefficient of Friction – The coefficient of friction of PTFE is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular PTFEcoating used. PTFE Coated Bolts are Nonwetting – Since surfaces coated with PTFE are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more thorough—in many cases, surfaces are self-cleaning. PTFE Coated Bolts are Heat Resistance – PTFE industrial coatings can operate continuously at temperatures up to 260°C/500°F. PTFE Coated Bolts have Cryogenic Stability – Many PTFE industrial coatings withstand severe temperature extremes without loss of physical properties. PTFE industrial coatings may used at temperatures as low as -270°C/-454°F. PTFE Coated Bolts are Chemical Resistance – PTFE is normally unaffected by chemical environments. The only chemicals known to affect all PTFE industrial coatings are molten alkali metals and highly reactive fluorinating agents.
