Special high-pressure gasket material for highest thermal and mechanical stresses
KLINGERSIL® C-4509 is a special high-pressure gasket material that offers excellent service in many sectors of the chemical industry. Main fields of application: alkaline media and steam. The expanded metal reinforcement is a galvanized low carbon steel insert which increases the compressive strength and pressure capability. Suitable for high-pressure applications because of its higher resistance against blowouts.
This material is manufactured with carbon fibers and special high-temperature resistance additives and reinforced with a nitrile binder.
