Rulon is the trade name for a family of PTFE plastics produced by Saint-Gobain Performance Plastics. Rulon plastics are known for their low coefficient of friction, excellent abrasion resistance, wide range of operating temperatures, 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 has a 1000 fold increase in wear resistance as compared to PTFE. However, it machines much like PTFE. It can also be moulded, extruded, skived, stamped, and hot and cold formed. Below is a table of properties pertaining to Rulon AR, but note that the other types of Rulon have similar properties.
