Conductive sponge

Conductive sponge is a dielectric material produced by polymer composite foaming technology, which has excellent conductivity and electromagnetic wave shielding properties. It is widely used in electronic devices to prevent electromagnetic interference (EMI) and other related electromagnetic wave interference.

Material characteristics

1. Conductivity: Conductive sponge is processed through special techniques to give its surface or interior conductivity, enabling it to conduct current or electromagnetic signals.
2. Uniform foaming pore size: The conductive sponge produced by foaming technology has a uniform pore size distribution, which helps to maintain the overall performance and stability of the material.
3. Soft and elastic: The conductive sponge has a soft and elastic texture, which can provide good cushioning and protection.
4. Corrosion resistance: Due to its material composition and special treatment process, conductive sponge usually has good corrosion resistance and can resist the erosion of chemical substances such as acid and alkali.

5. Not affected by temperature and humidity: The conductivity of conductive sponge is stable and not easily affected by temperature and humidity changes.
   

manufacturing process

1. Substrate selection: Polyurethane (PU) or polyethylene (PE) is usually chosen as the substrate.
2. Conductive treatment: Conducting the substrate through physical or chemical methods, such as PVD (Physical Vapor Deposition) or electro deposition of metals such as nickel and copper.
3. Forming processing: The processed material is subjected to processes such as foaming and cutting to form the desired shape and size.

application area

Conductive sponge has a wide range of applications in multiple fields due to its unique properties and advantages:

1. Electronic products: Conductive sponge is widely used in electronic products such as computers, LCD displays, LCD TVs, laser printers, high-speed copiers, communication equipment, mobile phones, etc., for electromagnetic shielding, anti-static, and protection of device pins.
2. Military and Aerospace: In the military and aerospace fields, conductive sponges also play an important role in protecting precision electronic equipment and instruments from electromagnetic interference and damage.
