Rulon Sheet Rod

Rulon® is a family of proprietary PTFE materials engineered for High performance self-lubricating applications.
Rulon materials combine high compressive strength, a low coefficient of friction, and excellent abrasion and corrosion resistance.

Rulon® is the trade name for a family of proprietary PTFE fluoropolymer compounds and other inert ingredients. This family of materials offers the combination of high compressive strengths, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication.

Rulon® is able to withstand temperature extremes of -400°F to over 500°F with and without additional lubricants, ideal In bearing and seal applications. Rulon® products are unique in that they do not cause stick-slip, or erratic low-speed motion. They also withstand a variety of harsh environments such as extreme dryness, cryogenic temperatures, water, steam, and hydrocarbon fuel. Rulon® products primarily are used for mechanical, electrical and chemical applications.

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[1] 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

Rulon ® Key Properties

This unique family of materials offers the combination of high compressive strengths, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication. These materials are used in bearing and seal applications at temperature extremes from -400°F to +500°F (-240°C to +260°C) with or without additional lubricants. Rulon ® materials also have the unique property of no "slip stick" --- no erratic motion at low speeds

Common Rulon ® Applications

Properties and types

There are many different types of Rulon produced for specific applications. These include:

• Rulon A, obsolete
• Rulon AR, maroon ,used for seals & stronger than Rulon LR
• Rulon LR, maroon , 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
• 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 fricion 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 PTFE However, it machines much like PTFE. It can also be moulded , extruded , skived , stamped , and hot and cold formed.
