We are a leading supplier of the very special fluid sealing products needed by the world's semiconductor manufacturers. Since the late 1980s we have worked with the industry's design engineers to develop new materials and fluid seals that will operate efficiently in the highly aggressive environments encountered.We precision mould 'O' rings of every size and to every standard, in a vast range of general and high performance elastomers. These include fluoroelastomers (eg, Viton® from DuPont Performance Elastomers), hydrogenated nitriles (our Elast-O-Lion® range), and compounds based on Aflas® from Asahi Glass - as well as nitriles, ethylene propylene, silicones and fluorosilicones. We stock over seven million 'O' rings for immediate despatch, and can manufacture and supply non-stocked items within days.
As authorised UK distributor for Kalrez® parts from DuPont Performance Elastomers, we design, supply and provide technical support for perfluoroelastomer sealing products and fluid handling components. Numerous grades of Kalrez® have been tailored specifically for semiconductor processes, including plasma and gas deposition applications, as well as thermal processes and wet processes.
We have vast experience of problem solving by the design and manufacture of seals and other components in our Fluolion® PTFE, as well as Vespel® and Zymaxx® from DuPont Performance Elastomers, PEEK™ from Victrex. and other exotic materials. Semiconductor industry applications with Vespel® include clamp rings, composite rings, baratron inserts, spacers and screws.
We swiftly produce precision cut gaskets and other complex profiles to any shape, size or quantity from any sheet material. Cutting capabilities include CAD/CAM controlled abrasive waterjet cutters and laser cutters that work from customers' CAD files, or scanned in drawings, templates or samples. All standard flange designs are held in memory.
Our leading jointing brands include Fluolion® Integra White & Blue (stabilised PTFE), Ultra High Purity Supagraf® expanded graphite, Chieftain® (carbon-fibre based), Centurion® (glass and aramid fibres), and Nebar® (cork-elastomer) grades. Specification and commercial grade elastomer sheets, including Kalrez® perfluoroelastomer from DuPont Performance Elastomers, are also widely used as gasket materials.
This is our greatest area of expertise. The research and development facilities of James Walker Technology Centre, combined with our world-class manufacturing capabilities for high performance elastomers and engineering plastics, enable us to approach any fluid sealing problem with confidence. Much of this high-level work is confidential, and we are accustomed to operating under these conditions and fully respect the issues involved.
High performance moulded products supplied to the semiconductor industry include barrel etcher seals, finger seals, door seals, lip seals, and plunger seals.
