Trelleborg Sealing Solutions launches Isolast® J9577, a perfluoroelastomer specifically engineered for aero engine seals. The material gives outstanding performance at high temperatures, offering best-in-class thermal stability, even in aggressive HTS oils, to provide extended seal life.

Isolast® J9577 has a continuous operating temperature range from -20°C/ -4°F to +325°C/ +617°F and is compatible with virtually all media including aggressive High Thermal Stability (HTS) oils. In a variety of tests to national and international standards as well as various customer specifications, the material demonstrated a step change in operating performance, most notably in terms of long term compression set.

"Thermal stability of sealing materials has become an increasingly important issue over recent years," says Paul Jones, Global Segment Manager Aero Engines, Trelleborg Sealing Solutions. "With the drive to improve efficiency and meet environmental needs, aero engines run at higher temperatures to reduce fuel burn, decreasing CO2 emissions and lowering operator costs. For these applications, Isolast® J9577 is the ideal sealing material choice with its outstanding high temperature performance and proven best-in-class thermal stability."

Isolast® J9577 is recommended for use in static applications and is available in standard profiles or custom designs. The material is part of the Isolast® range of proprietary perfluoroelastomers from Trelleborg Sealing Solutions. In addition to this material the range includes a number of compounds specifically engineered for the requirements of the aerospace, chemical processing, semiconductor fabrication and oil & gas industries.
