PROPERtIES AND APPLIcAtIONSDoniflex® GR-A is soft sealing material reinforced with tanged steel insert. Excellent thermal and stress resistance combined with very good adaptability to flange irregularities provides best service in high temperature and stress applications. It is recommended for sealing exhaust air supplies, pipes, intake and exhaust manifolds and exhaust gas recirculation systems in engines, as well as other industrial sealing applications that require high strength and thermal integrity i.e. for transmission flanges and high-pres-sure pumps.

Composite gasket material consisting of advanced graphite-based, “beater-addition” facing material mechanically bonded to a galvanized low carbon expanded mild steel insert with exceptional radial strength, significantly improved tensile strength and resilience.

PROPERtIES AND APPLIcAtIONSDoniflex® GR-EM is composite gasket material consisting of advanced graphite-based, “beater-addition” facing mate-rial mechanically bonded to a galvanized low carbon expanded mild steel. Due to expanded metal reinforcement, the gasket material features a number of outstanding properties when compared to conventional soft materials. It pro-vides exceptional radial strength, significantly improved tensile strength, resilience and other fluid resisting properties required of a reliable material capable of coping with higher combinations of pressure and temperature stress. The expanded metal reinforcement permits the optimization of surface pressure distribution on assembled gaskets.Thanks to optimum properties and dimensions of expanded metal reinforcement, the gasket material also exhibits high seal ability against gases at elevated temperatures. Doniflex® GR-EM can therefore be used as a general pur-pose material for many industrial sealing applications, as well as a high-performance gasket material for dynamically and thermally stressed joints. Typical applications include sealing of water, steam, oils, hydrocarbons and chemicals where the medium to be sealed allows the use of a zinc-galvanized steel reinforcement. It can be used in flanges, fit-tings, pumps, valves, exhaust systems, engines, vessels and heat exchangers in the automotive, petrochemical, pulp and paper, food and pharmaceutical industries, in power stations as well as in shipbuilding.
