Polytetrafluoroethylene, more commonly known as PTFE resists attack by heat and virtually all chemicals. Its electrical properties are excellent. Although it has high impact strength, its resistance to wear, tensile strength and creep resistance are low in comparison to other engineering type thermoplastics. Mechanical properties can be improved by adding fillers such as glass fibers, bronze, carbon and graphite.
PTFE Rod, Sheet and Tube exhibits the lowest electric constant and lowest dissipation factors of all solid materials. Because of its strong chemical linkage, PTFE Sheet, rod and tube shows very little attraction for dissimilar molecules. This results in a coefficient of friction as low as 0.05.

  • Inertness to most chemicals
  • Resistance to high temperatures
  • Low coefficient of friction
  • Excellent dielectric properties
  • Relatively insensitive to temperature
  • Relatively insensitive to power frequency
  • Zero moisture absorption
  • Excellent radiation resistance
