Plastic Shims and Gaskets offers a range of Cork gasket materials
made from clean, ground cork and combined with nitrile and polycloroprene
binders which are consistently uniform in quality and content.
The cellular construction of cork, together with the inherent properties
of rubber (natural and synthetic) present in "RUBBERISED CORK"
closely approach the perfect gasket material. More than 50% of cork's
volume is accounted far by air within the cork cells, hence compression
does not produce lateral spread and the high strength of the cell
walls ensures good recovery properties. The flowing characteristics
of rubber, its ability to withstand high vacuum and the action of
hot oils are all desirable features of a good gasket material. All
these properties are present in the range of rubberised cork Gaskets
manufactured by PSG.
Rubberised cork sheets are produced from top quality cork intimately
bonded with a synthetic rubber, which may be SBR, nitrile or neoprene
type. This provides a material in which the natural compressibility
of cork is combined with the resilience and mechanical strength
The chemical properties of the material are determined partly by
those of the cork and largely by the type of the rubber used. Cork
bonded with synthetic rubber such as neoprene can be used, amongst
other purpose, for crank case and inspection doors on diesel and
gas engines and for valve covers, sump, oil and water pumps on internal
combustion engines. It is also used for electrical transformers,
control gear, switch gear and cable boxes. The material is mostly
used at sustained operating temperatures not exceeding 120o C, Special
materials made up with silicone may be used in higher temperatures,
depending on environment.
