PTFE Molded Shapes

PTFE (PolyTetraFluoroEthylene) is a high molecular weight, fluorocarbon solid compound consisting wholly of fluorine and carbon. PTFE has a remarkably low coefficient of friction, exceptional chemical resistance, exceptional dielectric properties and good wear resistance.

PTFE is molded from a powdered resin in a closed die set at ambient temperature by applying high pressure, typically 3,000 to 4,500 psi, to create a preform shape. The preform is removed from the molding die and free sintered (heated) in programmable ovens at 685°F to 700°F to fuse the molecules into a solid form.

PTFE can be further enhanced by blending the resin with other materials creating unique compounds that exhibit better physical properties. Certain fillers and combinations of fillers can enhance the wear, friction, compressive strength, conductivity and creep resistance of PTFE. PFI specializes in the use of a virtually limitless range of fillers in our blended plastic compounds, such as:

  • Bronze
  • Carbon (Fiber or Powder)
  • Colorant (For visual identification)
  • Glass (Fiber or Bead)
  • Graphite
  • Molybdenum Disulfide
  • Polyimide
  • Ryton

PFI has other standard fillers available, and offers custom blended materials upon request.

At PFI, there are two types of PTFE molding that we specialize in:

  • Automatic Molding
  • Compression Molding

PFI has the resources, both in experienced staff and an extensive array of in-house equipment, to meet and exceed all your PTFE molding requirements, from the simple to the most complex and intricate. Contact PFI today with all your PTFE molding specifications.
