Which is better, anti-static foam or conductive foam?

 

Anti-static foam

Anti-static foam is produced after plastic particle polyurethane foaming. In order to ensure the stable anti-static performance of anti-static foam, carbon powder will be added. After adding carbon powder, it generally appears gray-black, and there are other colors.

 

The common anti-static foam in industrial production is made of PU, that is, anti-static foam made of polyurethane material, which is used in the electronics industry; in addition to PU material, there is also anti-static foam made of EVA, the Chinese name of EVA It is a butadiene-butyl acrylate prepolymer, which is an epoxy resin. The anti-static foam made of this material has the characteristics of excellent flexibility and ductility like vulcanized rubber; there are also XPE/IXPE anti-static foam. Cotton organic chemical high-density polyethylene foamed plastic is made of low-density polyethylene resin plus coupling agent and foam rubber through high temperature continuous polyurethane foaming.

conductive foam

The conductive foam can obtain a good shielding effect in the frequency range of 100KHz to 1GHz. The conductive foam has a conductive and anti-corrosion conductive fiber cloth, and is lined with a low-compression PU foam, which has a good shielding effect. The conductive fiber cloth is woven by metal fibers composed of Polyester fibers covered with copper and nickel metal surface layers. The combination of copper and nickel provides good conductivity and shielding.

 

Conductive foam is especially suitable for occasions with limited capacity and closing pressure, and the cost is low. It is especially suitable for high-performance shielding occasions requiring good fit. It can be widely used in electronic chassis, cabinets, indoor chassis, industrial devices, laptops, mobile communication devices, etc.

 

The advantages of conductive foam:

1. Good conductivity, high shielding effectiveness (≥80dB)

2. Good anti-oxidation and anti-corrosion properties

3. Good wear resistance and high reliability (≥1 million times)

4. Very soft, suitable for occasions that cannot provide greater pressure

5. The price is affordable, it is a very ideal shielding material

6. Simple and diverse installation methods, suitable for pasting and card slots

7. Products comply with ROHS, Halogen Free, REACH, requirements.
