PTFE (Polytetrafluoroethylene)

Polytetrafluoroethylene (PTFE) is a high molecular weight polymer with excellent thermal and electrical insulation properties, and a low coefficient of friction. It is a highly versatile plastic material useful in a broad range of high technology market segments and products, and its properties can be modified by additives such as glass fiber, carbon, or graphite.
