Properties and Performance of PTFE

PTFE has a distinctive profile that makes it one of the most precious and flexible materials available for engineering.

Biological inertness
Excellent weatherability
Excellent insulating properties
Non-stick, easy to clean
at low temperatures and thermal stability at high temperatures
Chemically resistant – all normal solvents, acids, and bases
Low dielectric constant and low dissipation factor
Low dynamic coefficient of friction
Broad working temperature range -180°C (-292°F) to 260°C (500°F)

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. PTFE resin does not flow when it melts and cannot be injection molded. The best method is molding and machining.

Modified PTFE

Modified PTFE is a chemically modified version of PTFE that has new capabilities in addition to the property characteristics consistent with virgin PTFE material.

Part surfaces are smoother, and less porous
Longer flex life than PTFE
Higher dielectric strength yields superior high-voltage insulation
Improved permeation resistance
Increased stiffness & improved creep resistance
Provides good chemical stability and broad chemical resistance
