Overview
Omniseal Solutions applies specialized processing expertise to polymer materials to address corrosion, chemical compatibility, friction and insulation challenges across industrial applications. Design starts with selecting the appropriate proprietary material grade and can deliver components or assembled systems that reduce weight and footprint while meeting application-specific performance requirements.

Materials

• Rulon® fluoropolymers (hundreds of grades)
• Meldin® high-temperature thermoplastics and polyimides
• Hycomp™ polyimide-based composites

Design & Manufacturing
The range includes standard geometries (bearings, piston rings, cup seals, guide rings, etc.) and fully custom parts co-developed with customers. Capabilities cover precision machining, molding, rapid prototyping, in-house testing and assembly. Parts can replace metal components to reduce mass and enable complex geometries and advanced processing methods. Typical components: bearings, rings, seals, piston rings, vanes, thrust washers, wear components, bushings, guide rings, wear liners, clamps and thermal isolators — sizes from miniature up to very large diameters as required.

Application examples & markets
