Oriented Wires in Silicone

Oriented Wires in Silicone Description:

Our S Range silicone rubbers combine excellent environmental protection with a high level of shielding effectiveness. These products incorporate a matrix of vertically oriented wires which pierce both flat faces of the elastomer and provide around 100 contact points per square centimetre.
The materials, which include solid (SP Series) and sponge (SS Series) variants as well as Flurosilicone (SF Series), sponge silicone flame retardant (SG Series) and solid silicone flame retardant (SR Series) options, are produced in sheet or strip form and are usually factory fabricated and diecut into gasket profiles to customers specifications.

The S Range is probably the most versatile of gasket materials. They provide good environmental protection and are regularly used where long service life, high performance fixed gaskets are needed. Because of the harder nature of the material, and because it needs a strong closing force through a relatively rigid cover which is screw fixed at regular intervals, they are not generally suitable for doorseals or other applications where a regular opening and closing application applies. The possible exception to this is the SS Series.
They are usually supplied in gasket, strip or sheet form with a pressure sensitive adhesive backing which holds the gasket in the absence of a groove or channel. If a groove is available the gasket form is often a jointed 'o' ring without the adhesive backing.
Because S Range elastomers are wider than they are high when specifiying the thickness should be stated first as this will be the length of the embedded wires. Then, if the height needs to be greater than the width (i.e. to fit into a groove), there will be no doubt about your actual needs.
Particular care needs to be taken over the design of gaskets to ensure that fixing covers or doors do not distort during compression. It is often necessary to incorporate 'limit stops' into the gaskets to prevent over-compression. The material should be compressed by approximately 15% of its relaxed height.
