Material
|
MatriCS consists of an St2LG (A366) steel
core 0.25 mm thick with a fiber-reinforced, high-grade NBR elastomer
coating with a thickness of 0.125 mm applied to both sides.
MatriCS plus
differs from MatriCS in that the core material is springy
stainless steel 1.4310 (301) with a thickness of 0.2 mm, and the
elastomer coating is somewhat thicker (approx. 0.15 mm).
|
Properties
|
In spite of their high mechanical strength and excellent stress
resistance, both materials feature high compressibility and
good recovery.
The materials’ good thermal resistance should also be mentioned. They
are particularly resistant to oils, fuels, antifreeze, refrigerants, and
non-polar solvents.
|
Application
|
- For sealed joints subjected to higher mechanical and thermal stress, e.g.
intake manifolds, oil pans, valve covers, transmission covers, axle
joints, engine ancillaries and valves, as well as for housing/cover
joints, compressors, pumps, hydraulic equipment, threaded couplings, plugs, etc.
- Gaskets with a continuous bead should be used for components that are flexurally weak and only permit low sealing pressures, have a poor
distribution of surface pressure, and with high sealing
demands, as they are highly conformable even with low bolt forces, and achieve excellent
sealing due to the resulting linear contact pressure.
Thanks to the springy core, beaded gaskets
made of MatriCS exhibit even better fatigue strength, recovery, and sealing properties.
|
Surfaces
|
MatriCS is delivered with a non-stick coating on both sides. Therefore, additional surface treatment is unnecessary in most cases.

The data quoted above are valid for the material "as delivered" without
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
contact us and specify the exact operating conditions.
