Conductive Copper Foil Tape with Conductive Adhesive for EMI Shielding
Copper foil tape is a kind of metal tape, mainly used in electromagnetic shielding, sub-electric signal shielding and magnetic signal shielding. Electric signal shielding mainly depends on excellent electrical conductivity of copper and magnetic shielding requires conductive material “nickel” of adhesive surface to achieve the function of magnetic shielding, which is widely used in mobile phones, laptops and other digital products.
One side of the copper foil tape is copper foil, the other side is isolation paper: the middle by the import of acrylic pressure-sensitive adhesive bonded.

General Knowledge about Copper Foil Tape
- Test conditions for the room temperature 25 ℃, relative humidity 65 ℃ following the United States ASTMD-1000 test results.
- When the goods are stored, please keep the indoor dry and ventilated, domestic copper storage time is generally 6 months, the importing country can be stored for longer and not easily oxidized.
- Products are mainly used to eliminate electromagnetic interference EMI, electromagnetic wave isolation on the human body hazards, mainly used in computer peripheral wire, computer monitors and transformers manufacturers.
- Copper foil tape is divided into single-sided adhesive and double-sided adhesive. Single-sided plastic coated copper foil tape is divided into single-lead copper foil tape and double-guided copper foil tape, single-conductor copper foil tape refers to the plastic surface is not conductive, only the other side of the copper conductive. Double copper foil tape refers to the plastic surface conductive, and the other side of the copper itself is conductive, it is said that double-conductor that is double-sided conductive. There are two-sided plastic coated copper foil tape and other materials used to be processed into more expensive composite materials, double-sided plastic coated copper foil’s surface is also divided into conductive and non-conductive. Customers can according to their own needs of the conductive to choose the product.
