CEMJO – Single >
Material Details
This material consists of a double perforated steel core with a layer of Non Asbestos beater material applied to each side. The beater material layer is bonded to the core by means of tangs which are clinched into the beater material body. These tangs are produced in the steel by perforating during manufacture.
The completed assembly is high resistant to heat and gas. Mechanical adhesion of the beater layer to the steel is such that the material cannot separate during handling or in operation. Various assembly thicknesses are available.
Application
Cylinder head gasket and manifold gaskets.
When used for cylinder head gaskets it is normal to have metal eyelets or grommets fitted to the bores and water holes. During manufacture these become embedded material, giving a gasket of uniform thickness

Material Details
Tin plate is mild steel sheet or strip, coated with tin for corrosion resistance.
Application
This grade of tin plate is primarily used for perforation purpose- double sided or single sided, especially for critical cylinder head gaskets. This can also be used as steel core for cylinder head gaskets with steel back bone design. Other usages are exhaust / inlet manifold gaskets, as cylinder head cover gasket core etc. Not suitable for forming applications.
