ASTM F436 Type1, A453 Gr 660 Cl A/B/C/D, Zeron 100
Over seventy years ago a DuPont scientist, discovered polytetrafluoroethylene. (PTFE) a fluoropolymer that is corrosive chemical and heat resistance, and the worlds most slippery surface. PTFE Coated Coated Washers 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 PTFE coating used.
PTFE Coated Coated Washers are Nonwetting since surfaces coated with PTFE are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more in many cases, surfaces are self-cleaning.
PTFE Coated Coated Washers 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 Coated Washers 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.
A wide variety of protective coating types are available to match the performance requirements of a specific application.
Fluoropolymer - Resin/lubricant blends that offer excellent corrosion protection
PTFE - The original non-stick coating, able to withstand high temperatures
FEP - PTFE characteristics with better abrasion resistance
PVDF - high quality coating ideal for chemical processing applications
ECTFE/Halar®️ - resistant to most chemicals plus high impact strength
PTFE is a combination of low-friction fluoropolymer compounds in a matrix of strong, stabile organic polymers. This fluoropolymer coating exhibits excellent surface wear characteristics along with the resistance to friction, heat, cold, corrosion and chemicals.
Fluoropolymer coatings are superior dry / solid film lubricants that produce a smooth, hard and slick finish. These coatings are applied using a one coat system that fuses the coating to the substrate for remarkable adhesion. In addition to very low coefficients of friction, fluoropolymers offer exceptional resistance to heat, cold, corrosion and chemical infiltration.
