What Are the Features and Properties of Copper Foil Tape?

Copper Foil Tape is a kind of metal tape mainly used for electromagnetic shielding, divided into two types: telecom signal shielding and magnetic signal shielding. Telecom signal shielding mainly relies on the excellent electrical conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" on the adhesive surface of copper foil tape to achieve magnetic shielding. Therefore, it is widely used in mobile phones, laptops, and other digital products.


1. Features of Copper Foil Tape


Copper foil has low surface oxygen characteristics and can adhere to various base materials such as metal and insulating materials. It has a wide temperature range and is mainly used for electromagnetic shielding and anti-static purposes. When the conductive copper foil is placed on the substrate surface and combined with the metal substrate, it has excellent conductivity and provides electromagnetic shielding effect.


The purity of copper foil tape is higher than 99.95%, and its function is to eliminate electromagnetic interference (EMI), isolate the harm of electromagnetic waves to the human body, and prevent the influence of unnecessary voltage and current on functions.


In addition, copper foil tape has a good effect on static electricity dissipation after grounding of objects. It has strong adhesion and good conductivity, and can be cut into various specifications according to customer requirements. Copper foil tape is widely used.


2. Performance of Copper Foil Tape


Copper foil tape has several properties, such as insulation, heat insulation, waterproofness, good adhesion, good cold resistance, easy tearing, and the ability to eliminate electromagnetic interference (EMI), isolate the harm of electromagnetic waves to the human body, and avoid the influence of voltage or current.


Copper foil tape is mainly used in computer monitors, peripheral cables and transformer manufacturing, central air conditioning pipelines, ventilation, refrigerators, water heaters and other pipeline joints, as well as precision electronic products, computer equipment, wires, and cables. It can isolate electromagnetic wave interference and resist high temperature to prevent spontaneous combustion during high frequency transmission.
