PTFE

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 Flexibility at low temperatures and thermal stability at high temperatures Non-flammability Chemically resistant – all normal solvents, acids, and bases Excellent weatherability 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.
