Evonik has developed the innovative polyether ether ketone (PEEK) powders VESTAKEEP®. It reduces 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 subjected to extreme requirements like

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.
Due 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
- 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 one of the leaders 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.
