Cork
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 of rubber.
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.
