Material Notes:
Description: Rulon® is the Saint-Gobain trade name for their family of proprietary PTFE compounds. This family of materials offers the combination of high compressive strength, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication. They are used in bearing and seal applications from temperature extremes of 400°F to over 500°F with and without additional lubricants. A unique property of Rulon® is the absence of stick slip, that is, erratic low-speed motion. PTFE = polytetrafluoroethyleneXL Grade Bearing/Seal PTFE: The best Rulon® against aluminum surfaces. Tan in color. Suitable for environments of steam, wet, dry, or vacuum type. Material has electrical and thermal insulation properties.Information provided by Saint Gobain Performance Products.
