paragraph 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...
