Teflon™ PTFE

Teflon™ PTFE (Polytetrafluoroethylene) Properties & Information

Teflon™ PTFE is a performance thermoplastic known for its chemical inertness & resistance to attack, low coefficient of friction, broad operating temperature range, excellent dielectric properties, thermal & electrical insulating, negligible water absorption and non-stick characteristic and among many others. Teflon™ PTFE is FDA Food Grade compliant.

PTFE resins have an upper service temperature of 500º F (260 C) and is the most widely used fluoroplastic material.  PTFE mechanical properties are low compared to other advanced engineering plastics, but its properties remain useful over a temperature range of -100° F to 400° F forming its broad operating range suitable for many applications. PTFE can be used as low as - 436º F (-260 C ). 

 PTFE properties are often enhanced using a variety of fillers creating a PTFE compound, such as a 15 or 25% glass filled PTFE,  to improve wear resistance, increase part stability, and improves creep  strength and reduce deformation under load in comparison with virgin grade PTFE. For electrical insulators, the addition of glass filler has little impact on electrical properties. 

The links below provide Teflon™ PTFE characteristics and general property information about two of the Teflon™ PTFE resins that APT compression molds and CNC machines into finished parts.

Teflon™ NXT 85 Modified PTFE is a chemically modified resin that offers improved resistance to deformation under load, increased resistance to permeation of chemicals, and higher dielectric breakdown strength in comparison with virgin PTFE.
