  • Detailed introduction

Copper foil tape

Copper tape is a kind of metal tape, which is 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 rubber surface of copper foil tape. The conductive material "nickel" is used for magnetic shielding and is therefore widely used in mobile phones, notebook computers and other digital products. Copper foil has a low surface oxygen property and can be attached to a variety of different substrates, such as metals, insulating materials, etc., and has a wide temperature range. Mainly used in electromagnetic shielding and antistatic high temperature resistant tape, the conductive copper foil is placed on the substrate surface, combined with the metal substrate, has excellent conductivity, and provides electromagnetic shielding effect. Can be divided into: self-adhesive copper foil, double-lead copper foil, single-lead copper foil, double-sided double-lead copper foil.

Performance parameter

The general inspection performance of the most commonly used copper foil tape on the market is as follows:

Material: CU 99.98% Substrate thickness: 0.009mm-0.1mm

Adhesive thickness: 0.035mm~0.04mm

Colloidal composition: ordinary pressure sensitive adhesive (non-conductive) and conductive voltage gram pressure sensitive adhesive

Peeling force: 1.0 ~ 1.5kg / 25mm (180 degree reverse peeling force test)

Temperature resistance -10°C---120°C

Tensile strength 4.5~4.8kg/mm

Elongation 7% to 10% MIN

The difference between double-lead copper foil tape and single-lead copper foil tape:

The double-lead copper foil tape has a conductive acrylic adhesive on one side and conductive properties on both sides; the single-lead copper foil tape has a non-conductive acrylic adhesive on one side, and the adhesive surface has no conductive property. It can be identified mainly from the following two aspects:

1. Appearance: double-lead copper foil tape, the back surface contains fine particles (metal particles, which act as conductive), which is slightly uneven; the single-lead copper foil backing surface has no fine particles, and is flat;

Foil tape

product manual

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. The material is polyester fiber, which is not easy to crack and damage after repeated use or multiple bending. It has strong adhesive force and good electrical conductivity. It can be easily wound and attached to the wire. It can be cut into various specifications according to customer requirements.

Use

Aluminum foil tape is suitable for all kinds of transformers, mobile phones, computers, PDAs, PDPs, LED monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.

It can be used in places where electromagnetic shielding is required in various electronic products such as PDAs, PDPs, LCD monitors, notebook computers, and copiers.

2. Imported aluminum foil tape is mainly used for the wrapping of cold (hot) gas pipelines, generally used for cold (warm) gas projects and water heater manufacturers.

3. Imported aluminum foil tape is used to match the joints of all aluminum foil composite materials, the sealing of the insulation nail puncture and the repair of the damaged parts.

4. It is the main raw and auxiliary materials for refrigerators and freezers production plants, and is also a must-have raw material for the insulation materials distribution department. Products are widely used in refrigerators, air, automotive, petrochemical, bridges, hotels, electronics and other industries.

5. Applicable to all kinds of transformers, mobile phones, computers, PDAs, PDPs, LCD monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.

6. Imported aluminum foil tape is used for steam pipe outer wrapping to prevent temperature from being lost.
