Freudenberg: Hard-particle increases friction...

Hard-particle increases friction coefficient of coatings


The technology group Freudenberg SE, Weinheim/Germany, has acquired the activities of the startup Frictins GmbH from Wolnzach/Germany – including Frictins’ innovative technology to increase the friction coefficient.

This allows lightweight and more compact component designs as well as the transmission of up to 5-times higher torque and shear forces. These features are of high relevance in applications within E-mobility and its increasing performance requirements regarding the connection of parts.
This technology combines an innovative hard-particle coating process with a special nonwovens from Freudenberg. The patent pending solution is using a multi-step-process to coat hard particles in various dimensions onto the surface of special nonwovens. When applied in the friction joint, the hard particles penetrate into both parts of the joining components and create a micro interlock. Compared to existing technologies on the market, Frictins’ technology offers a great flexibility in the design process, e.g. due to lower material thickness, while also providing high friction coefficient. By using 100% inert materials, this new technology cannot cause any corrosion between the joining parts
This technology is utilized by automotive manufacturers and suppliers in engine, chassis and powertrain applications.
Currently, the products are manufactured in pilot production scale in a facility near Munich/Germany. Freudenberg has acquired all assets and will set up an industrial scale production within the next few months.
