Flexible Copper Foil Adhesive Tape

Flexible copper foil adhesive tapes are usually made of electrolytic copper of high purity, which is calendered or electrolyzed to make thin sheets of copper foil. Copper foil has good electrical conductivity, thermal conductivity and ductility, and is the key material for the tape to realize various functions. According to different application requirements, a variety of types of adhesives can be used. The common ones are acrylate adhesives, silicone adhesives and rubber adhesives. Acrylate adhesives have good bonding strength and weather resistance; silicone adhesives have excellent high temperature resistance, can maintain good adhesive properties in a wide range of temperatures; rubber adhesives have good flexibility and initial adhesion.
Release material: In order to facilitate the storage and use of the tape, the surface of the adhesive will be covered with a layer of release material, such as release paper or release film. The release material has low surface energy, which can prevent the tape from sticking when it is not in use, and when it is in use, it is only necessary to tear off the release material to reveal the adhesive surface for sticking.

Flexible Copper Foil Adhesive Tape Features

High flexibility: this is one of the main features of flexible copper foil adhesive tape. Due to the use of thin and flexible copper foil and adhesive with good flexibility, the tape is able to maintain stable performance under various bending, folding or twisting situations, and is not easy to break or de-glue. It can be easily adhered to the surface of various irregularly shaped objects, such as curved circuit boards in electronic equipment, complex piping inside automobiles, and so on.
Excellent electrical and thermal conductivity: Copper foil has excellent electrical and thermal conductivity, which can effectively transmit current and emit heat. In the electronic field, it can be used for connecting electronic components, making electrodes, etc., to ensure the normal conduction of circuits; in occasions where heat dissipation is required, such as power amplifiers, power supply modules, etc., it can conduct heat out quickly, improve the heat dissipation efficiency of the equipment, and ensure its stable operation.
Good bonding performance: the adhesive is able to achieve a strong bond on different surfaces, whether it is metal, plastic or ceramic and other materials, can form a strong adhesion with the tape. This enables the flexible copper foil adhesive tape to reliably fix and connect objects in a variety of applications, and is not prone to falling off or loosening.
Corrosion and weather resistance: specially treated copper foil and weather resistant adhesive make the tape It can resist the erosion of moisture, oxygen, acid and alkali in the air, and keep the stability of performance under different environmental conditions, suitable for indoor and outdoor various environments.
