PTFE Key Properties
PTFE's mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of of -100°F to +400°F (-73°C to 204°C). Mechanical properties are often enhanced by adding fillers (see paragraph below). It has excellent thermal and electrical insulation properties and a low coefficient of friction. PTFE is not Melt Processible using extrusion or injection molding and is processed via sintering or ram extrusion due to it's high melt viscosity.

PTFE's mechanical properties can be enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze. Generally, filled PTFE's maintain their excellent chemical and high temperature characteristics, while fillers improve mechanical strength, stability, and wear resistance.
PTFE is inherently resistant to UV degradation and Highly Reflective to ultraviolet light, with Reflectivity greater than 85% in the spectral range of 240-300 nanometers. Up to 99% reflective in some cases. Which makes PTFE an ideal choice for UVC light reflective barriers for Far UVC and Germicidal UVC disinfecting systems.
