Rulon® XL
Rulon® Fluoropolymers

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.

In addition to the more tailor-made solutions offerings, for example, the Omniseal Solutions™ piston rings, typical offerings of Rulon® XL include automatically molded bearings and components, sleeve, flanged, and thrust bearings, stamped and formed seals, extruded shapes, machined parts, and molded shapes.

Applications include vacuum pumps, mixers, compressors, appliances, insulators, linear slides, shaft support, and wear bands. Rulon XL presents excellent outgassing capability for use in vacuum applications, but can also be used in steam, wet and dry environments.
