PTFE mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of -100F to +400F (-73C to 204C). 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 con not be melt processed - it must be compressed and sintered to form useful shapes.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. The properties of 25% glass-filled PTFE grade are shown below. 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.
