Rulon^® Fluoropolymers

XL PTFE

Rulon^® XL is a tan colored material that is best for use against aluminum (including anodized) substrates. Rulon^® XL exhibits very low wear as compared with other Rulon^® grades.

Other advantages offered by this unique material are that it combines low deformation under load with exceptionally good chemical resistance.
It is compatible with a wide range of mating surfaces, but is not recommended for use with alkalis. Its non-abrasive character enhances the frictional performance to prevent galling of softer mating surfaces.

It is the best material for vacuum service.

Rulon^® XL is the material for superior heat and wear resistance. Recommended for moderate to high speed dynamic service running against soft metals. Not recommended for applications with steam.
