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.
Benefits of PTFE
High thermal resistance
Very low coefficient of friction
High anti-stick properties
Available modified and filled
Available in shapes and films
Available in flexible tubing
