New Perlast Fluoroelastomer for Vacuum Deposition Processes at Intersolar North America
5th July, 2009

Intersolar North America - Leading semicon equipment seals company, Perlast Ltd is launching its latest 'clean', high performance fluoroelastomer (FKM) material for solar panel manufacture, at Intersolar North America (Booth no. 7128). Called V75SC, the elastomer is designed for CVD, PECVD and PVD vacuum deposition processes. It offers low particulation in these critical sealing applications, together with cost advantages over perfluoroelastomer seals.

The white colored, V75SC has a high fluorine content which provides thermal resistance up to 250 degrees C, combined with high levels of plasma and chemical resistance. In addition, it has a low compression set and modulus, ensuring maximum long-term sealing effectiveness. V75SC can be used for O-rings and formed seals in static and dynamic applications including door seals, slit valve seals, lip seals, check valves and pumps.

Perlast is able to offer V75SC in sizes up to 100 inch diameter, fully molded, O-rings and formed seals manufactured on a single tool, in one pressing operation, within a Class 10,000 clean-room facility. This provides repeatable, dimensionally accurate, moldings, negating the quality issues seen with manual "endless" molding techniques and jointed O-rings.

"With V75SC we are driving up the performance level that engineers can expect from their fluoroelastomer seals in the chemically and mechanically demanding locations seen on solar panel manufacturing equipment," said David Holt, director of business development, Perlast Ltd.
