TRIBOFORCE®

Tribologically optimized compounds

TRIBOFORCE® is our product series of tribologically op-timized compounds. With a complex combination of different additives, these materials define a new class in wear behaviour. Exceptional wear resistance and low coefficients of friction, coupled with excellent dimen-sional stability, make TRIBOFORCE® the ideal material for bearings to withstand extreme requirements.

A broad polymer and temperature spectrum

Users can choose between TRIBOFORCE® materials with different base polymers, covering a temperature range of - 40 °C to 260 °C, and short-term service temperatures of up to 300 °C are even possible as well.

Excellent sliding and bearing materials

TRIBOFORCE® materials are the preferred materials for toothed wheels, slidings and bearings, and in almost all cases, it is possible to get by without lubrication. By substituting our new additive combinations for conventional lubricants such as PTFE, we are also able to produce TRIBOFORCE® materials with a high mechanical strength.

Practical tribological tests

In addition, users can have wear measurements carried out on tribological test rigs. Virtually all the operating conditions speci-fied by the customer can be simulated on the test rig, permitting the friction and wear behaviour to be established in this way. Elaborate test series can then be dispensed with.

Application Options

The product series is used, e.g., for components in the automotive industry, machine and plant construction, materials handling technology, industry, sports and leisure, etc., as
