Evonik has launched a new tribological material, designed especially for use in #slidebearings needing to withstand high-temperature and high-pressure environments. Based on PEEK (polyether ether ketone), the VESTAKEEP® Easy Slide 2 product can be used either as a polymer coating in hybrid bearings, or as a full PEEK-based bearing, depending on the application. The material is ideally processed by injection molding, but also can be extruded.

“Our latest launch of the #VESTAKEEP® Easy Slide 2 material is part of our business line’s strategy to expand the range of tribological applications for our innovative PEEK-based products. This includes working with customers in the industrial, medical and robotics industry to solve their especially challenging needs,” says Christopher Studte, head of the Industrial #PEEK segment at Evonik’s High Performance Polymers business line.

VESTAKEEP® Easy Slide 2 is produced without any intentionally added #fluoropolymers such as PTFE. Fluoropolymers are commonly used in polymer-based slide bearings for their desirable properties.

“Comprehensive test data has shown VESTAKEEP® Easy Slide 2 to have #superiortribologicalproperties – especially in its resistance to high temperatures, pressure and velocity – when compared to other polymer-based slide bearing materials on today’s market,” says Philipp Kilian, research and development Program Manager for PEEK in Evonik’s High Performance Polymers business line. “Additionally, VESTAKEEP® Easy Slide 2 demonstrated excellent results compared to other polymer bearings – as well as traditional metal bearings - in dry-run and lubricated slide bearing tests at various temperatures.

“Our PEEK-based VESTAKEEP® Easy Slide 2 is a superb material for slide bearings, #thrustwashers and also #seals in challenging conditions,” says Studte. “Customers will benefit from the product’s light weight as well as its improved energy-efficiency and noise dampening in many applications. VESTAKEEP® Easy Slide 2’s compatibility with injection molding will also give customers increased cost-efficiency, especially when scaling up to produce large quantities.

#Evonik will make its extensive test data on VESTAKEEP® Easy Slide 2’s friction and wear properties available to customers, so they can ensure optimal calibration of the material for their specific application.
