Polytetrafluoroethylene (PTFE), discovered by DuPont in 1938, has two primary properties that contribute to invaluable and versatile uses in a range of industrial, architectural and high technology applications. First, PTFE is inert, making it unreactive to virtually any chemical. Second, it offers one of the most slippery materials available, a characteristic which can be used for an advantage in numerous applications. Porex’s PTFE products have a low coefficient of friction and excellent thermal, electrical, mechanical and chemical properties. They offer the ideal choice for a wide variety of demanding applications requiring one or a combination of these exceptional properties.

With a linear molecular structure of repeating – CF2-CF2-units, PTFE is a crystalline polymer having a melting point of about 621°F (327°C) and exceptional resistance to chemicals. Available in sheet/membrane form and custom molded geometries, Porex’s porous PTFE is UL rated for continuous use to 480°F and is available with mean pore sizes ranging from 2 micrometers to 50 micrometers.
