Materials

These composite solutions are high temperature, polymer-based materials that are reinforced with glass or carbon fibers. They are used as a replacement for metal due to weight saving properties and eliminating lubrication need in applications with high mechanical requirements. Suited for aviation critical systems such as engine, flight control, landing gear, wheel and braking, applications vary from bushings, guide rings, wear liners, seals, clamps, and thermal isolators.

Rulon^® 488 is a dull turquoise material originally developed for use with painted surfaces. It has been used in veneer dryer bearings in the plywood industry.

Its excellent wear resistance, especially in extremely dry environments, make it a material of choice in hydrogen and natural gas compressors. Its almost universal chemical resistance enables it to withstand corrosives and acids sometimes present in trace amounts in these environments.

Rulon^® is a tan material made entirely from FDA and USDA compliant components. It has excellent physical properties and is chemically compatible with most chemicals, except concentrated sulfuric acid. This offers much flexibility in wash-down environments of food and pharmaceutical processing environments.

It has slightly lower coefficient of friction than Rulon^® J, offering extended life and less abrasion with softer mating surfaces.

It is compatible with most commercially available natural lubricants for additional reduction in friction.

Rulon^® 1439 is a white FDA and USDA compliant material that is suitable for immersed service (submerged applications with superior wear characteristics than most other PTFE compounds). Its color makes it aesthetically pleasing for food and pharmaceutical applications.

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.

Rulon^® 945 is a black PTFE-based material that has very low wear and deformation under load, making it ideally suited for demanding thermal applications. In fact, its deformation is the lowest of all Rulon^® grades. It also possesses excellent chemical resistance and good dimensional stability

Since Rulon^® 945 has moderate abrasive qualities, this black material is best suited for use against hard mating surfaces, like hardened steel substrates. It is not suitable in applications where electrically insulating properties are required.

The legacy material range of Omniseal Solutions, the Meldin^® 2000 series, offers excellent tensile strength and elongation, high compressive strength, and strong dimensional stability.

The Meldin^® 6000 Polyimide (PI) Based series from Omniseal Solutions offers self-lubrication, long durability under high temperature and load, and high resistance to radiation and chemical environment. 

A thermosetting polyimide, the Meldin^® 7000 material series exhibits extremely high dimensional stability at elevated temperatures. Testing has shown that Meldin^® materials have less than 0.04% variation from their original dimensions after cycling from 73°F (22.77°C) to 500°F (260°C) over a two-day period.

The Meldin^® 8000/9000 Polyimide (PI) Based series is a specific range of material formulations, used in bearing cages, for example, due to its strength and its low coefficient of friction. It is a porous structure filled with lubricant.
