  0100 – Virgin PTFE
    Virgin PTFE has the best chemical resistance and lowest coefficient of friction of any of the material choices. Its purity also makes it suitable for food contact applications. (FlexiSeal®)
   
  0102 — Modified Virgin PTFE
    Same basic properties as virgin, but with increased wear and creep resistance and lower gas permeability.
   
  0307 — Carbon-Graphite Filled
    Carbon reduces creep, increases hardness and elevates thermal conductivity of PTFE. Carbon-graphite compounds have good wear resistance and perform well in non-lubricated applications.
   
  0502 — Carbon Fiber Filled
    Carbon fiber lowers creep, increases flex and compressive modulus and raises hardness. Coefficient of thermal expansion is lowered and thermal conductivity is higher for compounds of carbon fiber filled PTFE. Ideal for automotive applications in shock absorbers and water pumps. (FlexiSeal®, FlexiCase™)
   
  0601 — Aromatic Polyester Filled
  Aromatic polyester is excellent for high temperatures and has excellent wear resistance against soft, dynamic surfaces. Not recommended for sealing applications involving steam. (FlexiSeal®)
   
  0204 — Molybdenum Disulfide and Fiberglass Filled
    Molybdenum disulfide increases the hardness of the seal surface while decreasing friction. It is normally used in small proportions combined with other fillers such as glass. MoS2 is also inert towards most chemicals. (FlexiLip™, FlexiCase™)
   
  0203 — Fiberglass Filled
    Glass fiber has a positive impact on creep performance of PTFE. It also adds wear resistance and offers good compression strength. (FlexiSeal®)
   
  0301 — Graphite Filled
    Since graphite is often used as a lubricant, it does not significantly increase the coefficient of friction of PTFE when used as a filler. The low friction allows the compound to be used when both shaft speed and pressure are high. Graphite also is chemically inert which enables its use in corrosive medias.
(FlexiSeal®, FlexiLip™, FlexiCase™)
   
  0120 — Mineral Filled
    Mineral is ideal for improved upper temperatures and offers low abrasion to soft surfaces. PTFE with this filler can easily be qualified to FDA and other food-grade specifications.
   
  0405 — Stainless Steel Filled
    Although stainless steel filler is very abrasive, this compound has excellent extrusion and high temperature resistance in static and slow dynamic applications.
   
  0615 — Proprietary Low Wear PTFE
    This proprietary filled PTFE offers low wear and friction properties, used in general applications where long life is required. Not recommended for applications with abrasive media. (FlexiLip™, FlexiCase™)
     
  0602 — Ryton/Carbon Filled
    Ryton/Carbon filled PTFE features improved surface lubricity and abrasion resistance. It should be used only on shafts hardened to 60Rc or more. (FlexiSeal®)
     
  0512 —Carbon Fiber Filled
    Carbon fiber lowers creep, increases flex and compressive Modulus and raises hardness. Coefficient of thermal Expansion is lowered and thermal conductivity is higher For compounds of carbon fiber filled PTFE. Ideal for automotive applications in shock absorbers and water pumps. (FlexiLip™)
     
  0127 — Mineral Filled
    Mineral is ideal for high temperatures and offers low abrasion to soft surfaces. PTFE with this filler can easily be qualified to FDA and other food0rade specifications.
