Greene Tweed’s Chemraz SFX Engineered for Subfab Applications

Greene Tweed, a manufacturer of high-performance elastomers, thermoplastics, composites, and engineered components, recently announced that its Chemraz SFX perfluoroelastomer has been specially engineered to withstand the corrosive environments commonly seen in subfab applications while reducing the risk to health, safety, and the environment from toxic emissions.

Chemraz SFX, a custom engineered FFKM, is ideal for sealing system upgrades because it has been designed to withstand harsh chemicals and high temperatures encountered in subfab environments. Chemraz SFX features broad chemical resistance to typical subfab effluents and optimized physical properties for long life in static vacuum fittings. With an operating temperature range up to 300°C (572°F), it’s available as a standard O-ring as well as a custom seal design and dramatically improves seal performance at high temperatures.

Greene Tweed has designed a custom seal assembly specifically for use in the subfab environment, including pumps, abatement systems, and exhaust piping. The custom design, combined with Chemraz SFX, overcomes the limitations of KF fittings, which can lead to elevated stress in seal materials and premature failures. Using the custom assembly with Chemraz SFX also enables users to upgrade systems using conventional sealing materials (e.g., fluoroelastomers) that can no longer handle the temperatures or chemical exposure found in today’s subfab applications.

Chemraz SFX matches seal performance to the application, thereby increasing productivity through reduced failures and maintenance needs. Applications include pumps, flanges, valves, and abatement systems. A high-performance perfluoroelastomer with highly temperature-resistant material and patented high-temp ISO fitting designs, Chemraz SFX offers enhanced performance at a low cost of ownership.
