1. Conductive silicone rubber

Conductive silicone rubber is made by uniformly distributing conductive particles such as silver plated glass, aluminum, and silver in the silicone rubber, and contacting the conductive particles through pressure to achieve good conductivity. Its main function is sealing and electromagnetic shielding. The product can be molded or extruded, and there are options for sheet packaging or other die cut shapes. The shielding performance is as high as 120 dB (10 GHz).

Conductive silicone rubber must withstand a certain amount of compression force to conduct electricity well, so the structural design must ensure appropriate pressure without overpressure. The optimal height compression of the board is 7-15%; The optimal height compression for solid circles and D-shapes is between 12-30%; The optimal height compression for tubular and P-shaped structures is between 20-60%.

2. Conductive cloth

Conductive cloth material is made by chemically depositing or physically transferring metal nickel onto polyester fibers, then plating a highly conductive copper layer on top of the nickel, and electroplating nickel metal that is resistant to oxidation and corrosion on top of the copper layer. The combination of copper and nickel provides excellent conductivity and good electromagnetic shielding effect, with a shielding range of 100K-3GHz.

3. Conductive foam

Conductive foam is wrapped with conductive cloth on flame-retardant sponge, and after a series of treatments, it has good surface conductivity, which can be easily fixed on the device to be shielded with adhesive tape. There are shielding materials available in different cross-sectional shapes, installation methods, UL ratings, and shielding effectiveness.

4. Conductive cloth tape

Conductive cloth tape is a backing adhesive with high conductivity, which has excellent flexibility, suitable for various surfaces, and can withstand high temperatures up to 200 ° C.

5. Conductive shielding tape

Conductive shielding tape is a type of metal foil or conductive cloth with high conductivity backing adhesive. Its conductive backing adhesive and conductive substrate form a complete conductive body, which can be bonded to any metal surface to achieve electrical overlap and electrical sealing of gaps. Shielding conductive tape is an economical and convenient shielding material.

Used to seal EMI shielding chambers, shells, and electronic equipment seams, wrap cables for shielding, provide reliable grounding surfaces, and provide electrical contact for surfaces that cannot be welded.

6. Microwave absorbing materials

Microwave absorbing materials are materials that can absorb microwaves and electromagnetic energy with minimal reflection and scattering (commonly known as spikes in EMC laboratories). Also known as radar absorbing material or radar stealth material. The basic principle of absorbing microwaves is to convert microwave energy into other forms of motion energy through a certain physical mechanism, and convert it into thermal energy through the dissipation effect of this motion. All forms of lossy motion excited by microwaves can serve as absorption mechanisms. Common mechanisms include electrical induction, magnetic induction, electromagnetic induction, and electromagnetic scattering.

7. Conductive coating

metallic or non-conductive surfaces the characteristics of absorbing, conducting, and attenuating electromagnetic waves like metals, thereby playing a role in shielding electromagnetic wave interference.
