RUBBER AND SPONGE GASKETS
Rubber has found itself used in many industrial duties because it provides and
maintains elastic properties across a wide range of process conditions and temperatures.
As a specialist supplier of seals
and gaskets our development in rubber technology has remained progressive, with rubber
lending itself so readily to so many sealing applications. Whilst no single grade has all
the desired properties, indeed some properties may only exist in one type of rubber, by
understanding the service conditions a suitable grade can generally be selected from
stock or achieved through careful compounding to a newspecification.
Most natural and synthetic grades of rubber are also available in sponge form (cellular
rubber) in both open and closed cell grades. Open cell will absorb fluid, such as a car
washing sponge; varying densities and materials of open cell can be used for packaging,
acoustic and sound insulation, filters and low pressure duty dust tight seals. Closed
cell sponges do not readily absorb fluid and make excellent gaskets in cut or strip form
where lighter compressive loads and/or uneven flange faces exist, to make effective low
cost dust and low pressure fluid seals.
SEP can supply all rubber and sponge materials in:
Sheet/Roll – commercial, specification & diaphragm
grades;
Gasket, Diaphragm, Strip or Die/Cad-Cam cut shape up to 100mm
thick
Tape – to specified width & thickness with or
without pressure sensitive adhesive backing;
Fabricated forms – segmented, dovetailed, vulcanised
joints;
Extrusion and Moulded Shapes – see SEP brochure
‘Manufacturing in Rubber’.
Special application requests show our ultimate flexibility. Where a requirement exists
for a commercial or specification grade of rubber, thickness, hardness and colour that is
not readily available or economical; we have the ability to mould the material in
economic sheet, disc or ring sizes and then cut the gasket within the same factory
– and if required on the same day.
