FJ2602 consists of a tanged stainless steel core with a layer of fiber-reinforced mica material applied to both sides. The core is made of a 0.20 mm thick stainless steel sheet (material 1.4828). Apart from expanded mica, the coating contains high-temperature-resistant fibers and a small amount of high-quality elastomers as binding agents.

Due to the use of mica and the heat-resistant 1.4828 mm stainless steel core, FJ2602 withstands high temperatures up to 950 °C.

This combination gives FJ2602 an excellent sealing potential over the full temperature range. Its high compressibility and elasticity gives it good adaptability, allows it to compensate optimally for component distortions (macro-adaptation), and it also displays constant material behaviour under alternating operating conditions. The tanged steel core lends the material a high resistance to pressure, i.e. low setting tendency.

FJ2602 is resistant to media such as oils, fuels, exhaust gases, antifreeze, and many other chemicals. For extreme mechanical loads and sealing requirements, we recommend the use of a stainless steel inner bead.

Applications

As a material for the exhaust system in any IC engine (e.g. truck engines, marine diesel engines, gas engines) for fitting between the cylinder head and manifold, and in the downstream flanged joints of exhaust systems, for turbocharger seals or EGR (exhaust gas recycling) gaskets, especially for the purpose of complying with stringent emission limits.

It may also be used for sealed joints on burners in heating systems, high-temperature heat exchangers, gas turbines, and other applications.

For extreme mechanical loads and sealing requirements, we recommend the use of a stainless steel inner bead.
