PTFE is a fluorocarbon-based thermoplastic polymer that is a popular choice for sealing solutions. This material offers excellent wear resistance, elasticity, and frictional properties.

Increasingly, fillers are being used to improve the performance of PTFE materials. Adding a filler to a PTFE formulation, such as carbon or bronze, can significantly increase the material's mechanical properties.

A common example of this is the addition of carbon fiber to a PTFE material. The added carbon fiber increases the compressive strength and flexural modulus of the PTFE material.

Another filler commonly added to a PTFE material is molybdenum disulfide. Molybdenum disulfide enhances the PTFE material's electrical properties, and lowers its frictional resistance.

The molybdenum disulfide also increases the thermal conductivity of PTFE and reduces its permeability, making it suitable for appliances needing low permeability.

PTFE can be filled with various types of fillers, including carbon, glass fiber, and bronze. The type and percentage of the filler will affect the performance of the material.
