Material
|
Xtreme plus 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.
|
Properties
|
Due to the use of mica and the heat-resistant 1.4828 stainless steel core, Xtreme plus withstands high temperatures up to 950 °C.
This
combination gives Xtreme plus 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.
Xtreme plus is resistant to media such as oils, fuels, exhaust gases, antifreeze, and many others.
|
Application
|
- 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. In addition to increased
internal pressure loading capability, cross-sectional sealing, and
blow-out safety, it also provides improved resistance to chemicals.

any additional treatment. In view of the countless possible
installation and operating conditions, definitive conclusions cannot be
drawn for all applications regarding the behaviour in a sealed joint.
Therefore, we do not give any warranty for technical data, as they do
not represent assured characteristics. If you have any doubt, please
