Question: Is silicone conductive?

General silica gel is non-conductive, only conductive silica gel can conduct electricity.

Conductive silica gel is to uniformly distribute conductive particles such as nickel-coated copper powder and silver powder in the silica gel, and make the conductive particles contact by pressure to achieve good conductivity. There are military and commercial applications, and its main role is sealing and electromagnetic shielding.

Products can be molded or extruded and available in sheet or other die-cut shapes with shielding performance up to 120 dB (10 GHz). Conductive silica gel has good electromagnetic sealing and water vapor sealing ability, and can provide good conductivity under certain pressure (suppression frequency reaches 40GHz).

Scope of application

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

2. Conductors for bottom contact such as keyboards and keys;

3. Photocopier roller;

4. Wire connection pipe;

5. When the volume resistance of the conductive silica gel is less than 10 ohm cm, the conductive silica gel has the function of electromagnetic shielding. That is, the volume resistance is less than 10 ohm cm. It is mainly used in electromagnetic shielding occasions, and is also used in electronic and microwave waveguide systems such as chassis, cabinets, shelters, power transmission and transformation projects, and connector gaskets.

The production process of conductive silicone is basically the same as that of ordinary silicone buttons and silicone products. They all require processes such as material preparation, molding, printing, spraying, and edge removal. Moreover, the operation methods and craftsmanship are completely the same as those of silicone button products. , but the conductive silicone has one more process, which is to add conductive materials, and these conductive materials may have some problems when they are formed or removed, because the production process of conductive silicone is still more complicated than the production of ordinary silicone products!
