Trelleborg Sealing Solutions has released Isolast J9876, a new perfluoroelastomer with specific properties for use in mechanical seals. This compound removes the need for multiple material grades supporting different applications. It has the most comprehensive media resistance at elevated temperatures of any perfluoroelastomer on the market, resulting in excellent long-term physical property retention.
Isolast J9876 is compatible with virtually all media, suitable for high-temperature applications and for use in steam and water. Compliant to USP Class VI, it can be used in pharmaceutical applications.
“The new Isolast J9876 material represents a breakthrough,” 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, allowing longer exposure to high temperatures and chemical contact without losing the mechanical properties that make it a great sealing compound.”
Isolast J9876 has a continuous operating temperature range from +19 degrees F to +527 degrees F/-7 degrees C to + 275 degrees C with peaks up to +599 degrees F/+315 degrees C. The compound is available in any size O-Ring, gasket, moulded part or rubber-to-metal bonded components, including door and gate seals. It is great for chemical processing systems, pumps, valves, power generation equipment, refineries and semiconductor applications not directly exposed to plasma sources.
