Copper foil has low surface oxygen characteristics and can be attached to a variety of different substrates, such as metals, insulating materials, etc., and has a wide temperature range. It is mainly used in electromagnetic shielding and antistatic. The conductive copper foil is placed on the substrate surface, combined with the metal substrate, has excellent conductivity and provides the effect of electromagnetic shielding. Can be divided into: self-adhesive copper foil, double-conductor copper foil, single-conductor copper foil, double-sided double-conductor copper foil and so on. There are various thicknesses to choose from: 0.018mm; 0.025mm; 0.03mm; 0.05mm; 0.06mm; 0.075mm; 0.08mm; 0.1mm; 0.13mm; 0.2mm and so on. Length: 50 meters; Width: 3mm--420mm can be customized. Use and description of conductive copper aluminum foil tape: PDA, PDP, LCD monitor, notebook computer, copier and other electronic products where electromagnetic shielding is required.
It is used to wrap steam ducts to prevent the temperature from being lost to the outside. Non-conductive copper foil tape Usage and description: Replaces enameled wire, various types of transformer shielding. Copper foil tape is mainly used in electromagnetic shielding, electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly depends on the excellent conductive properties of copper itself, while magnetic shielding requires the conductive material "nickel" on the rubber surface of copper foil tape. Achieve magnetic shielding, so it is widely used in mobile phones, laptops and other digital products. The general inspection performance of the most commonly used copper foil tapes on the market is as follows: Copper foil tape material: CU 99.98% substrate thickness: 0.018mm-0.05mm adhesive thickness: 0.035mm ~ 0.04mm colloid composition: ordinary pressure-sensitive adhesive ( Non-conductive) and conductive acrylic pressure-sensitive adhesive peeling force: 1.0 ～ 1.5kg / 25mm (180 degree reverse peeling force test) Temperature resistance -10 ℃ --- 120 ℃ Tensile strength 4.5 ～ 4.8kg / mm Extension The growth rate is 7% ～ 10% MIN.
