Conductive silicone rubber is obtained by uniformly distributing conductive particles such as nickel-coated copper powder and silver powder in silicone rubber, and contacting the conductive particles by pressure to achieve good electrical conductivity. It is used both in military and commercial applications, its main role is sealing and electromagnetic shielding.
The product can be molded or extruded and available in sheet or other die cut shapes with shielding performance up to 120 dB (10 GHz). Conductive silicone rubber has good electromagnetic sealing and water vapor sealing ability, and can provide good conductivity under a certain pressure (the suppression frequency reaches 40GHz).
Application:
1. Power tube, stress relieving glue and cable plug for cold-shrinkable cable accessories and heat-shrinkable cable accessories;
2. The bottom contact conductor such as keyboard and button;
3. Photocopying machine roller shaft;
4, wire connection tube;
5. When the volume
resistance of the conductive silicone rubber is less than 10 ohm cm, the
conductive silicone rubber has an electromagnetic shielding function. That is,
the volume resistance is below 10 ohm cm, which is mainly used for
electromagnetic shielding. It is also used in electronic and microwave
waveguide systems such as chassis, cabinet, square cabin, power transmission
and transformation engineering, connector gaskets, etc.
Conductive silicone rubber is basically the same as ordinary silicone rubber
buttons and silicone products in the production process. It is required to
prepare materials, form, print, spray, and detach the edges. The operation
method and craftsmanship are also the same as those of silicone button
products. However, there is one more process for conductive silicone, which is
to add conductive materials, and these conductive materials may appear in some
situations when molding or detaching, because the conductive silicone is more
complicated than ordinary silicone products in the production process!
