Evonik develops new PEEK powders for tribological coatings
Greater efficiency thanks to lower friction: The innovative polyether ether ketone (PEEK) powders VESTAKEEP® developed by Evonik significantly reduce the wear and tear of components in demanding industrial applications.
PEEK powders for demanding applications
The PEEK powders of Evonik's VESTAKEEP® brand are particularly suitable for applications that are subject to extreme mechanical, thermal and chemical requirements. The coating material is able to withstand permanent operating temperatures of up to 250°C and is characterized by its unique ability to resist abrasion and chemicals.
Thanks to the excellent tribological performance of coatings made from specially developed VESTAKEEP® powders , the friction between sliding surfaces is significantly reduced, which in turn increases efficiency and economy of operation – for example lower fuel consumption and lower CO2 emissions in combustion engines, extended service life of bearings, or higher turbine speeds. These special VESTAKEEP® coatings also allow for employing more cost-efficient substrate materials for components used in applications with sliding friction.
High performance in powder form
The various VESTAKEEP® PEEK powders are comprised of particles with average particle sizes ranging from 5 to 110 µm. They can be applied by flame and electrostatic spraying methods, or as aqueous dispersions. With electrostatic application, layer thicknesses can range from 20 and 300 µm; dispersions are suitable for thinner layers.
Based on over forty years of experience, Evonik has been a leader in the development and production of high performance polymers. VESTAKEEP® PEEK powders are part of the high-temperature polymers product portfolio offered by the Resource Efficiency Segment.
