PTFE offers a unique blend of chemical and temperature resistance, coupled with a low friction coefficient. PTFE is virtually chemically inert, and is able to withstand exposure to extremely harsh environments. The coefficient of friction for PTFE, the lowest of all fibers, makes the fiber suitable for a wide range of applications such as bearing replacement material and release material when stickiness is a concern.

The fiber's low friction coefficient, as well as their low tensile strength, makes PTFE difficult to process, and difficult to blend with other fibers. The material is also made into breathable, porous membranes laminated to fabrics for protective uses.
