Electrically Conduction Rubber Washer

Conduction Rubber Washer

Electrically Conduction Rubber Washer, also called Conduction Rubber Sheet,  Conduction Rubber Gasket, Conduction Rubber Ring Washer etc. which is made of silicone rubber materials with conductive particale like graphite, nickel, glass silvering, sliver-plate aluminum, copper etc, in aim to reduces or eliminates the EMI/RFI (electromagnetic interference and radio frequency interference) noise that is often associated with electronics.

Major Conduction Silicone Rubber Materials Types:

CONSIL-NC (graphite nickel plating filled in silicone rubber)
CONSIL-V (silver filling silicone rubber extrusion padding)
CONSIL-A silicone rubber (aluminum silver)
CONSIL-N (nickel plated silver filled in silicone rubber)
CONSIL-C silicone rubber (copper plating silver)
SC-CONSIL (graphite filled in silicone rubber)
CONSIL-R silicone rubber (fine silver)
CONSIL-II (silver filled in silicone rubber molded gasket)

Notes:
Conduction Silicone rubber Washer has electromagnetic shielding function, when the volume resistance is less than 10 ohm.cm. Mainly applied in electromagnetic shielding occasion, also used in the chassis, cabinets, shelter electronic and microwave waveguide system, connector pad, etc.

Conductive Silicone O Ring：Generally, the lower the resistance, the higher the hardness. When the resistance is below 10ohm.cm, the hardness mostly over 70 shore A.
If conduction silicone rubber Washer made by compression mold tool, the surface of rubber compression mold tooling should electroplate coating for easily release conduction rubber gaskets from silicone rubber mold tooling.

Conduction Silicone Rubber Washer Applications
Electrically Conduction Silicone Rubber Washer often refers to washer in rubber material, whose volume resistance is within 10^9 ohm.cm. Conduction silicone rubber can provide a good electrical conductivity (Inhibition of frequency 40 GHZ) with its good electromagnetic sealing and water vapor sealing ability. Its volume resistivity can be 0.004 ohm. cm, with good stability.
Electrically Conductive Silicone Rubber Washer is used in both military and commerce. Main function is to seal and electromagnetic shield. Products can adopt compression molding or extrusion molding. It is on chip or other cutting shape. Shielding performance is as high as 120 dB (10 GHz). Conductive rubber Washer is also used in medical electrode. Volume resistance of conductive rubber is bigger compared with that of metal, based on volume resistance is proportional to the distance, the longer the distance, the greater the resistance. Conductive Silicone Rubber Washer has been widely used on the medical electrode. Electrode is thinner, generally below 1 mm, conductive rubber is completely electrified in this case.
