Copper foil tape is a metal tape, mainly used for electromagnetic shielding, electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while magnetic shielding requires the adhesive of copper foil tape. The surface conductive material “nickel” can achieve the role of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products.
Product description: The purity is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the damage of electromagnetic waves to the human body, and avoid affecting functions due to unnecessary voltage and current. In addition, it has a good effect on electrostatic discharge after grounding. It has strong adhesion and good electrical conductivity, and 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.

The general inspection performance of the most commonly used copper foil tapes on the market is as follows: Material: CU 99.98%
Base material thickness: 0.007mm-0.075mm
Adhesive thickness: 0.015mm~0.04mm
Colloid composition: ordinary pressure-sensitive adhesive (non-conductive) and conductive acrylic pressure-sensitive adhesive
Peel force: 0.2~1.5kgf/25mm (180 degree reverse peel force test)
Temperature resistance -10℃—120℃
Tensile strength 4.5~4.8kg/mm
Elongation 7%~10%MIN
1. The test conditions are room temperature 25°C and relative humidity below 65°C using the results of American ASTMD-1000.
2. When storing the goods, please keep the room dry and ventilated. The domestic copper is generally stored for 6 months, and the importing country can store it for a longer time and is not easy to oxidize.
3. The product is mainly used to eliminate electromagnetic interference (EMI) and isolate the harm of electromagnetic waves to the human body. It is mainly used in computer peripheral wire, computer monitor and transformer manufacturers.
4. Copper foil tape is divided into single-sided and double-sided. The single-sided adhesive-coated copper foil tape is divided into single-conductive copper foil tape and double-conductive copper foil tape. ; Double-conductive copper foil tape refers to the conductive surface of the glue, and the copper itself on the other side is also conductive, so it is called double-conductive or double-sided conductive. There are also double-sided adhesive-coated copper foil tapes that are used to process more expensive composite materials with other materials. Double-sided adhesive-coated copper foils have conductive and non-conductive surfaces. to choose.
