Materials

Along with precision components, Omniseal Solutions provides high-performance materials that are included in the top tier of the polymer pyramid

Rulon® Fluoropolymers: We are the only source of authentic Rulon® materials since its creation in the early 1950s for industrial use. Available in hundreds of formulations, the material has been made into bearings, piston rings, cup seals, and wear components for other industries: aviation, space and life science. Technology advantages include low coefficient of friction, high wear life, chemical inertness, and extreme temperature / pressure properties.

Hycomp Composites: Including H310®, H320® and Wearcomp® solutions, these carbon fiber materials are mainly used in applications that require high temperature resistance, mechanical strength, or superior wear resistance. Up to 50% composites by weight are used in aircraft and helicopters (wings, landing gear doors, and structural elements). This material is also used in industrial and heavy machinery: canning, extrusion and forging.

Meldin® Polyimides & HT Thermoplastics: Our versatile, polyimides are used in aviation, industrial, semi-conductor, space, and life science. As it can be softened and cooled into a hard piece, it can be made into bearings, wear components, piston rings, thrust washers, seals, rods, sheets and tubes. This unique process is reversible and can be repeated. Unlike thermosets, our thermoplastics are insoluble after curing and designed to perform without external lubrication, allowing customers to extend part life or reduce weight.

Hycomp Composites

H310® & H320® 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.

1337 PTFE

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.


Used in
Easily withstands the chemical washdown procedures required of the food processing and pharmaceutical industries.

Rulon® Fluoropolymers

XL PTFE

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.
