Rulon AR
Rulon® Fluoropolymers

Rulon® AR is a light maroon colored material best known as the current version of the first Rulon® introduced, namely Rulon A. While often compared to another in the series, Rulon® LR, it is somewhat more flexible than its counterpart, and is therefore suitable for seals and bonded coating of slide surfaces, especially when those applications require higher physical properties than Rulon® LR can provide. It is also practically chemically inert, and provides long life and reliability in continuous non-lubricated service.

This filled PTFE material offers a combination of high compressive strength, a low coefficient of friction, chemical resistance, electrical insulation, and excellent abrasion and corrosion resistance without the need for lubrication. It is capable at operating at PV values up to approximately 10,000. Higher PV values are possible for intermittent use applications.
