To design and manufacture various types of components, Omniseal Solutions™ relies on the exceptional properties of a large portfolio of proprietary materials: Rulon®, Meldin®, and Hycomp™.
The design of a component can be defined in two different ways. Either the application requires a standard shape (e.g. bearing, piston ring, cup seal, etc…) and in this case, an Omniseal Solutions™ engineer can apply standard rules of design. Alternatively, the component requires a bespoke or custom design and in this situation, the team codevelops the solution with the customer. This could include, for example, defining the most efficient processing method to get the full benefit from the switch from a metal to a polymer. These additional benefits can be technical, economical, or both.

Examples
Meldin® Polyimides
High Temperature Polymer Material Solutions
Meldin® polyimide material solutions exhibit high dimensional stability at high temperatures and longer life at higher loads and speeds. With Omniseal Solutions™, total control on the process from the powder to the parts is guaranteed. Solutions include bearings, wear components, piston rings, vanes, thrust washers, and of course seals. This is in addition to custom shapes, rods, sheets, and tubes. These solutions are found in a multitude of industries such as aviation, industrial, semi-conductor, space, and life science.
Used in
where high thermal resistance and good mechanical properties are required
Meldin® Polyimides
7000 PI Based
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.
Used in
able to withstand thermal shocks very well and has extremely high dimensional stability
Rulon® Fluoropolymers
Engineered Proprietary PTFE Compounds
Omniseal Solutions™ is the only source of genuine Rulon® blended PTFE filled materials since the creation of Rulon® A, the first blended PTFE material, in the early 1950s. Available in hundreds of formulations, the material can be custom designed into bearings, piston rings, cup seals, wear components, and many other critical parts for different industries.
Used in
When low friction or high wear life / abrasion resistance is needed.
Rulon® Fluoropolymers
J PTFE
Rulon® J is an all-polymeric reinforced, dull gold colored PTFE compound that operates exceptionally well against soft mating surfaces such as 316 stainless steel, aluminum, mild steel, brass and other plastics. The unique “shaft friendly” material is also low in friction and wear, and self-lubricating.
Used in
Polymer filled material solution used for low friction, soft shaft and extreme cold temperature.
Hycomp™ Composites
Engineered Polyimide-Based Composite Materials
Hycomp™ composite materials are made from high temperature thermoset polymers and long carbon or glass fibers for applications requiring high temperature resistance, high mechanical strength and superior wear resistance.
Used in
when high temperature / wear resistance or high mechanical strength is needed
Hycomp™ Composites
Wearcomp® Materials
This composite solution is a high temperature, polymer-based material that is reinforced with glass or carbon fibers. It is 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 as well as wheel and braking, applications vary from bushings, guide rings, wear liners, seals, clamps, and thermal isolators.
Used in
general industry applications, especially in the steel and canning industry where its high shear and wear resistance properties provide the most value
