What is conductive silicone?

Conductive silicone is to uniformly distribute nickel powder, copper powder, silver powder and other conductive particles in the silicone. The conductive particles are contacted by pressure to achieve good conductivity. It is widely used in military and commercial fields.Its main function is sealing and electromagnetic shielding.

The product can be molded or extruded, with sheet or other punching shapes to choose from, with a shielding performance of up to 120 dB (10 GHz). Conductive silica gel has good electromagnetic sealing and water vapor sealing capabilities, and can provide good conductivity under a certain pressure (suppression frequency reaches 40GHz).

Conductive silica gel is basically the same as ordinary silica gel buttons and silica gel products in terms of production process. It requires materials preparation, molding, printing, spraying, and edge removal, and the operation method and craftsmanship are exactly the same as those of silica gel button products. , It’s just that the conductive silicone has one more process, which is to add conductive materials, and these conductive materials may appear a little when forming or removing the edges, because the production process of conductive silicone is still more complicated than ordinary silicone products.

Range of application

1. Power pipes, stress evacuation glue and cable plugs for cold-shrinkable cable accessories and heat-shrinkable cable accessories;

2. Bottom contact conductors such as keyboard and keys;

3. Roller shaft of photocopier;

4. Wire connecting pipe;

5. When the volume resistance of conductive silica gel is less than 10 ohm cm, conductive silica gel has the function of electromagnetic shielding.The volume resistance is less than 10 ohm, mainly used in electromagnetic shielding occasions, but also used in case, cabinet, square cabin, power transmission and transformation engineering and other electronic and microwave waveguide system, connector gasket, etc.
