Material NameCompound %Main PropertiesColor
PTFE/Very low coefficient of friction and excellent chemical resistance.

FDA approved.

White
Glass Filled PTFEUp to 40%Improved ware resistance, compression strength, creep resistance, chemical resistance. Good performance in oxidising environment, good creep resistance.White cream
Carbon Filled PTFEUp to 35%Improved electrical and termal conductivity, resistance to load, low coefficient of friction in dry, water, steam applications, chemical resistance. Superior ware resistance increase and low friction properties.Black
Graphite Filled PTFEUp to 25%Improve wear resistance, decrease friction and increase sliding properties against soft metals- chemical inertness. Improve the temperature resistance in some way.Black
Bronze Filled PTFEUp to 60%Improved compression strength, wear resistant, high thermal conductivity, resistance to abrasion. Reduced chemical resistance.Dark Brown
