The purity is higher than 99.95%. Its function is to eliminate electromagnetic (EMI) interference, to isolate the electromagnetic wave from harming the human body, and to avoid the need for voltage and current to affect the function. In addition, it has a good effect on static discharge after grounding. It has strong adhesive force and good electrical conductivity. It can be cut into various specifications according to customer requirements.

Uses: Suitable for all kinds of transformers, mobile phones, computers, PDAs, PDPs, LCD monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.

It is a kind of metal tape, mainly used for electromagnetic shielding, split signal shielding and magnetic signal shielding. The electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while the magnetic shielding requires the conductive surface of the copper foil tape. Nickel "is used to achieve magnetic shielding, and is therefore widely used in mobile phones, notebook computers and other digital products. The general inspection performance of the most commonly used copper foil tape on the market is as follows: Material: CU 99.98%
