Aluminum Tap Roll for Electromagnetic Shielding

The purity of aluminum insulation tape is higher than 99.95%. Its function is to eliminate electromagnetic interference, isolate the electromagnetic waves from harming the human body, and avoid affecting the function without voltage and current. In addition, it has a good effect on the discharge of static electricity after grounding.

Aluminum tape roll is suitable for all kinds of electronic products such as transformers, mobile phones, computer peripherals, PDA, PDP, LED displays, copiers, etc. where electromagnetic shielding is required.

Why can the aluminum foil tape shield electromagnetic signals? Aluminum foil is a kind of the conductive metal foil, which have electromagnetic shielding effect, and the shielding effect has no direct relationship with the thickness, but is related to the structure of the shielding material itself.

The reason why aluminum foil has electromagnetic shielding effect is because it and the surrounding metal constitute a closed shielding space.

Specifically, the shield body(aluminum foil) is used to surround the interference sources of components, circuits, assemblies, cables, or the entire system to prevent the electromagnetic field from spreading out. The receiving circuit, equipment or system with a shield(aluminum oil) to prevent them from being affected by external electromagnetic fields.

For getting better shielding efficiency, alu foil tape is usually coated with conductive glue. Generally, the shielding effectiveness of aluminum foil tape with conductive adhesive can reach more than 90dB, and only about 40dB with non-conductive adhesive.

The self adhesive aluminium tape is of great thermal conductivity and is resistant to chemical corrosion. It is generally used as a pipe sealing and thermal insulation material. Haomei Aluminum has 1235 and 8011 aluminum tape roll, if you need, welcome to inquire from us.
