- Evonik launched VESTAKEEP Easy Slide 2, a PEEK-based tribological material for high-temperature, high-pressure slide bearing applications.
- The compound is produced without intentionally added fluoropolymers such as PTFE.
- It can be processed by injection molding or extrusion and used as a polymer coating in hybrid bearings or as a full PEEK bearing.
- Test data indicates high pressure-velocity (pv) resistance and favorable friction and wear in dry-run and lubricated tests across temperatures.
Product overview
Evonik launched VESTAKEEP Easy Slide 2, a PEEK-based tribological material designed for slide bearings that must withstand high temperatures and high pressures; it can be applied as a polymer coating in hybrid bearings or used as a full PEEK bearing.
Material and processing
The formulation is produced without intentionally added fluoropolymers such as PTFE and is compatible with injection molding and extrusion, supporting cost-efficient scale-up for large-volume production.
Performance
Extensive test data indicate high pressure-velocity (pv) resistance and favorable friction and wear behavior in both dry-run and lubricated conditions across a range of temperatures, with comparisons made to other polymer and traditional metal bearings.
Applications and data
Suggested uses include slide bearings, thrust washers and seals where lower weight, noise damping and improved energy efficiency are desired; Evonik will provide customers with the test data needed to calibrate the material for specific applications.
