s, and chemical inertness. Common applications for Rulon include seals, piston rings, bearings, and electrical insulation.

History

Rulon, not to be confused with Mulon, was produced by Dixon Industries Corporation in 1952. and named after its then President, Robert Rulon-Miller. This first type of Rulon was dubbed "Rulon A" (which was later replaced with type AR). Dixon was then bought by the Furon company. Furon was purchased by Saint-Gobain Performance Plastics.

Properties and types

There are many different types of Rulon produced for specific applications. These include: *Rulon A, obsolete *Rulon AR,

maroon Maroon ( US/ UK , Australia ) is a brownish crimson color that takes its name from the French word ''marron'', or chestnut. "Marron" is also one of the French translations for "brown". According to multiple dictionaries, there are var ...

, has low deformation characteristics *Rulon J, gold, polymer filled for more abrasion resistance and softer mating surface *Rulon 641, white, U.S. Food and Drug Administration compliant *Rulon W2, used in fresh water applications *Rulon 123, FDA compliant with low and consistent friction characteristics *Rulon 488, inorganic filler used for compatibility with most surfaces *Rulon 957, green speckled, bearing grade with noise dampening characteristics *Rulon XL, tan, low friction; suitable for aluminium; excellent outgassing characteristics for use in

vacuums A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often dis ...

*Rulon F, green, polymer filled with excellent anti-abrasion characteristics *Rulon 142, aqua, low deformation material for used in linear bearings and slides *Rulon 945, black, very low deformation characteristics for use in high heat and impact applications *Rulon 1045, gold, highly elastic and moderately deformable for use as bearings, rings and seals *Rulon 1337, tan, FDA compliant with low coefficient of friction and excellent chemical resistance *Rulon 1410, gold, highly elastic *Rulon 1439, white, FDA compliant for use in submerged applications with low wear characteristics Rulon A has a 1000 fold increase in wear resistance as compared to
