  Product Description   About PTFE Virgin P.T.F.E. is the most common form and has some unique features which, apart from its  good slip characteristics, the advantages of this high performance product lies less in its  mechanical than in its thermal, electrical and chemical properties. Unfilled P.T.F.E can be  characterised by the following properties: Chemically inert  Insoluble in all known solvents below 300ºC  High thermal stability, continuous service temperature range -270º to 260ºC  Low coefficient of friction  Outstanding electrical and dielectric properties  Resistant to stress cracking and weathering  Limited use in structural components because of low modulus of elasticity  Poor wear resistance  Poor mechanical strength  Non toxic EU and FDA approval for food contact applications  Very high specific gravity  Easy to machine Properties About PTFE filled with Graphite   Graphite Filled P.T.F.E maintains the same levels of chemical resistance as virgin grade which results  in excellent resistance to corrosive environments but also exhibits good initial wear in rubbing  or sliding wear applications in both dry and wet operations. It is frequently used in piston rings  to reduce cylinder wall wear by entrapping abrasive foreign particles in the relatively soft surface. The percentage of carbon can range from 5% to 20%    Specification for " Conceptfe " Rod
