Tetron GR is an advanced engineering plastic from Dotmar’s Tetron range of filled PTFE materials. It combines PTFE with glass fibres and graphite to significantly improve wear resistance and mechanical properties while retaining the inherent low friction and chemical inertness of PTFE.
The addition of glass and graphite reduces deformation under load and minimises wear, making Tetron GR suitable for dynamic applications. It has a coefficient of friction as low as 0.1, excellent chemical resistance, and a service temperature range of -200°C to 260°C.
Dotmar supplies Tetron GR in a variety of stock shapes including rod, sheet and cylinder, machined to your specifications. Our technical team can assist with material selection and fabrication to ensure reliability in your application.
Key Features
- Glass and graphite filled PTFE for enhanced wear resistance
- Low coefficient of friction (0.1) for reduced stick-slip
- Wide service temperature range: -200°C to 260°C
- High chemical resistance across most aggressive media
- Reduced thermal expansion for improved dimensional stability
- Available as rod, sheet and cylinder for machining flexibility
Tetron GR is widely used for bearings, bushings, wear pads, guide rails, seals and piston rings in chemical processing, oil and gas, automotive, and general engineering industries. Its combination of low friction, chemical resistance and dimensional stability makes it ideal for components exposed to aggressive environments and frequent load cycling.
