TFV

Virgin PTFEEPM home of the seal man Virgin PTFE TFV

Also referred to as:
PTFE®, Virgin PTFE®, PTFE, TFE, TFV, Polytetrafluoroethylene

Color:
White

Temperature limits:
-328 to 500°F
-200 to 260°C

Information:
Use in: Packings, gaskets, seals, washers, spacers, insulators, wheels, rollers, bearings, guide rings.

Description: An extremely low friction material which remains stable at both low and high temperatures. The chemical resistance of this material is outstanding. Can be used in applications with extreme temperatures, extreme pressures and extreme chemicals. Since PTFE® TFV has a tendency to cold flow and has no memory. It can be filled or mixed with glass, bronze, and nickel to enhance its properties.

Characteristics: Semi-rigid plastic material. Most of the time it is finished by machining.

Technical Description:  Discovered in 1938 by Dr. Roy J. Plunkett of the DuPont Company, PTFE is a fluorocarbon-based polymer. PolyTetraFluoroEthylene is commonly abbreviated PTFE, and the PTFE brand of PTFE is manufactured only by DuPont. the fluoroplastic family offers plastics with high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation, and “slipperiness”.

General Properties:  PTFE mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of -100°F to +400°F (-73°C to 204°C). Mechanical properties are often enhanced by adding fillers (see filled grades below). It has excellent thermal and electrical insulation properties and a low coefficient of friction. PTFE is very dense and cannot be melt processed – it must be compressed and sintered to form useful shapes.

Filled Grades:  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. There are literally dozens of different filled PTFE products and grades – too many to be listed here. Please contact EPM for more information about other filled PTFE products for your application.
