en.Wedoany.com Reported - German chemical company Evonik has introduced a new PEEK-based material, VestaKeep Easy Slide 2, specifically designed for high-temperature and high-pressure sliding bearing applications. This material can be used as a coating for hybrid bearings or as full PEEK bearings, is suitable for injection molding processes, and can also be produced via extrusion.
Christoph Stute, Head of Industrial PEEK at Evonik's High Performance Polymers business line, stated that the launch of VestaKeep Easy Slide 2 aims to expand the tribological application range of PEEK-based products. Stute said, "This strategy includes collaborating with customers in the industrial, medical, and robotics sectors to address their particularly challenging needs."
The company emphasized that this PEEK-based material is produced without intentionally adding fluoropolymers like PTFE, which are commonly used in polymer-based sliding bearings. Philipp Kilian, R&D Project Manager at Evonik, pointed out that test data shows VestaKeep Easy Slide 2 outperforms other polymer-based sliding bearing materials in terms of high-temperature resistance, high-pressure resistance, and high-speed tolerance. Kilian said, "In dry-running and lubricated sliding bearing tests at various temperatures, the material also demonstrated excellent results compared to other polymer bearings and traditional metal bearings."
This new PEEK-based product also offers advantages such as lightweight, high energy efficiency, and noise reduction performance. Its compatibility with injection molding helps customers improve cost-effectiveness, especially when scaling up production. Evonik stated that it will provide customers with extensive test data on the friction and wear characteristics of VestaKeep Easy Slide 2 to support its performance in sliding bearing applications.
