Trelleborg Sealing Solutions launches Isolast® J9876, a new perfluoroelastomer with specific properties for use in mechanical seals. This new compound removes the need for multiple material grades supporting different applications. Its excellent long-term physical property retention results from the fact that it has the most comprehensive media resistance at elevated temperatures of any perfluoroelastomer on the market.
A breakthrough in mechanical sealing
Isolast® J9876 is compatible with virtually all media, suitable for high-temperature applications and for use in steam and water. Its compliance to USP Class VI means it can be used in pharmaceutical applications.
“The new Isolast® J9876 material represents a breakthrough in mechanical sealing,” says Steven Farnsworth, CPI Processing Equipment Segment Manager for Trelleborg Sealing Solutions Americas. “It is engineered to provide a balance between outstanding thermal performance and media compatibility. It offers a perfect fit for mechanical seal elements with its improved compression set and higher temperature capabilities. The two features work together to allow the material longer exposure to high temperatures and chemical contact without losing the mechanical properties which make it a great sealing compound.”
High temperature capabilities
Isolast® J9876 has a continuous operating temperature range from +19°F to +527°F/ -7°C to + 275°C with occasional peaks up to +599°F / +315°C. The compound is available in any size O-Ring, gasket, molded part or rubber-to-metal bonded components, including door and gate seals. In addition to mechanical seals, Isolast® J9876 is also a great choice for chemical processing systems, pumps, valves, power generation equipment, refineries and semiconductor applications not directly exposed to plasma sources.
The new material is part of the Isolast® range of proprietary perfluoroelastomers from Trelleborg Sealing Solutions. In addition to this universal material, the range includes a number of compounds specifically engineered for the requirements of the chemical processing, semiconductor fabrication and oil & gas industries.
