Composed of pigments and fillers such as glass, carbon, graphite and metal powders (bronze and molybdenum disulfide), Fluon® Filled PTFE Compounds are molding powders that enhance wear resistance, creep resistance, thermal conductivity and electrical conductivity over virgin PTFE resins. Compounds also preserve several properties unique to PTFE including low coefficient of friction, excellent chemical resistance and a wide service temperature range.
Glass-filled PTFE, the most universally used filled PTFE compound, can be utilized at service temperatures from -268 °C to +260 °C in chemical service ranging from liquid oxygen to fuming nitric acid, in severe wear pads for railway cars, and for self-lubricating compressor rings for non-aluminum cylinders. The most common applications include bearings, gaskets, V-rings, O-rings, back-up rings, hydraulic ring seals, non-lubricated compressor rings, valve seats, valve liners, swivel liners, thrust washers, lip seals, standoff insulators and feedthrough insulators.
Pelletized compounds, produced in an environmentally friendly manner, are easily processed in automatic molding equipment and are used primarily in automotive parts. Non-pelletized compounds are used in applications that demand the highest mechanical strength.
