TECAPEEK ® PVX black

PEEK modified

TECAPEEK PVX black is a modified Victrex® PEEK 450G material classified in the same performance category as Victrex® PEEK™ FC30. We supplement the PEEK base polymer with 10% each of PTFE, graphite, and carbon fiber. That makes TECAPEEK PVX an ultra high performance bearing material that incorporates the properties of a premium polymetric matrix material, with optimum levels of specific wear enhancing additives. It is ideally suited for technical bearing and wear applications. This PEEK modified formulation raises the continuous use temperature by approximately 4°C and increases the limiting PV dramatically, while maintaining excellent chemical resistance. When used as a non-metallic bearing, PEEK PVX offers a superb range of tribological performance characteristics. TECAPEEK PVX black is designed to run at high loads and speeds in hostile environments, and can either be run dry or with an external lubricant.
