Saint-Gobain Rulon® 1439 Bearing/Seal PTFE
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: Rulon® 1439 is a white FDA compliant material that is suitable for immersed service with better wear characteristics than most other PTFE compounds. Its color makes it aesthetically pleasing for food and pharmaceutical applications.

This material is also resistant to many harsh chemicals found in the application environments where it is typically used. It is compatible with most commercially available lubricants for additional reduction in friction. Its properties allow it to be effectively utilized as a bearing or sliding surface.

Vendors: TriStar Plastics Corp. provides engineering, custom fabrication and manufacturing of high-performance plastics and self-lubricating bearing materials, such as Rulon, PEEK, Torlon, CJ Composites and Ultracomp. Capabilities include component design, material selection, prototype and production, manufacturing and surface modification. Call (800) TRI-STAR (800) 874-7827 or visit or www.TStar.com
