Teflon™ PTFE Granular Molding Powders

More Options for Molding Diverse Products and Stock Shapes

Teflon™ PTFE (polytetrafluoroethylene) granular powders increase processing flexibility for molding different products and stock shapes, such as rods, tubes, and sheets. Products fabricated from Teflon™ PTFE powders benefit from their superior electrical properties and chemical resistance.


To process Teflon™ PTFE granular molding powders, prepare and sinter a preform and then fabricate functioning machined parts from the sintered stock shape.

Filled compounds can be produced from powders by mixing 5 to 40% (by weight) inorganic fillers to enhance properties such as:

  • Reduced wear and friction
  • Increased thermal and electrical conductivity
  • Improved resistance to cold flow
  • Elevated stiffness and thermal dimensional stability


PTFE is compacted at an ambient temperature into a handleable form (preform). Typical preform pressures, ranging from 3,000 to 4,500 psi with variable dwell times, can maximize end-use performance. Preform stock shapes at the appropriate pressure to ensure they do not exhibit inferior physical properties.


Remove the preform from the mold and heat above the melting point at a very controlled ramp rate (sintering). This coalesces the PTFE particles into a strong, homogeneous structure. Use a programmable oven to ensure adequate sintering. Raise temperatures slowly from room temperature to between 363 and 382 °C (685 and 720 °F). The part's geometry and dimensions dictate hold times at these temperatures.

Lower oven temperature at a controlled rate to achieve the desired degree of crystallinity in the molded shape. Improperly sintered shapes may result in inferior physical/electrical properties, permeation, and chemical resistance.

Features and Benefits

Teflon™ PTFE powders are rated for continuous service at 260 °C (500 °F) and provide exceptional low-temperature toughness and flame resistance.
