Properties and Performance of PTFE
PTFE has a distinctive profile that makes it one of the most precious and flexible materials available for engineering.
Flexibility at low temperatures and thermal stability at high temperatures
Chemically resistant – all normal solvents, acids, and bases
Low dielectric constant and low dissipation factor
Excellent insulating properties
Low dynamic coefficient of friction
Non-stick, easy to clean
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.
