Material Data Sheet
Material: Tecapeek™ PVX
PolyetheretherketoneTecapeek™ PVX is an ultra high performance bearing materials that incorporates the properties of a premium polymetric matrix material with optimum levels of specific wear enhancing additives. This formulation raises the continuous use temperature by approximately 40°F and increases the limiting PV while maintaining excellent chemical resistance. When used as a non-metallic bearing, Tecapeek™ PVX offers a superb range of tribiological performance. It is designed to run at high loads and speeds, in hostile environments, either dry or lubricated. Tecapeek™ PVX's exceptional properties make it an ideal material for bearing surfaces in the most demanding applications and in the harshest conditions.
