Ensinger has been developing high-performance thermoplastic compounds for moving components since 1966. With their lubrication integrated into the plastic, they are designed for dry-running systems that are particularly low-maintenance or even completely maintenance-free. In lubricated systems, they also improve emergency running properties in the event of insufficient lubrication.
The tribologically and mechanically optimised compounds from Ensinger under the TECACOMP TRM brand stand for excellent sliding properties, maximum strength and minimum wear. They are used in demanding industries such as automotive and mechanical engineering or in the oil and gas sector.
Examples of applications include:
Example: Recirculating air valve

Graphite (GR) consists of carbon and has very good dry lubricating properties. It also increases the compressive strength of the compound and improves shrinkage isotropy.
Molybdenum disulphide (MoS2) is a crystalline mineral with low friction coefficients in dry running. Similar to graphite, it consists of space-parallel crystal layers that are easily displaceable against each other, which leads to a lubricating effect.
Silicone oil (SI), unlike mineral oil or vegetable oil, is not based on organic carbon, but on silicon. It does not tend to resinify even at high temperatures (up to 180 °C) and forms a continuous lubricating film on the surface.
Castor oil (CO), also known as ricinus oil, is obtained from the seeds of a spurge plant (Ricinus communis). It has a high temperature resistance and has proven itself as a natural lubricant in tribological applications.
Polytetrafluoroethylene (PTFE) is a semi-crystalline, thermoplastic polymer with high resistance. It forms a lubricating film between the sliding partners and equalises static and dynamic friction. This usually prevents “stick-slip”.
Carbon fibres (CF) in the compound ensure maximum mechanical strength. Their graphite-like surface also has good lubricating properties. This reduces wear on the mating partner in tribologically stressful applications.
Glass fibres (GF) increase the tensile and compressive strength of the compound as well as its heat resistance. However, the hard fibre can increase abrasion in the system if the mating partner is made of a softer material.
