Product Introduction
Copper foil Mylar tape is a metal composite tape which is made of single-sided or double-sided copper foil as the base material, polyester film as the reinforcing material, bonded with polyurethane glue, cured at high temperature, and then slit. Mylar tape can provide high shielding coverage and is suitable for the overall shielding layer outside the cable core of control cable, signal cable. Other cable products that have higher requirements for shielding performance, and the outer conductor of coaxial cables.
Copper foils Mylar tape can make the signal transmitted in the cable better free from electromagnetic interference and reduce the signal attenuation during the data transmission process, so that the signal can be transmitted safely and effectively improve the electrical performance of the cable.
We can provide single-sided/ double-sided copper foil Mylar tape. The double-sided copper foil Mylar tape is composed of a layer of polyester film in the middle and a layer of copper foil on both side. The double-layer copper reflects and absorbs the signal twice, which has a better shielding effect.
The copper foil Mylar tape we provided has the characteristics of high tensile strength, good shielding performance, and high dielectric strength, etc. Compared with aluminum foil Mylar tape, it has better shielding performance.
Application
Mainly used as the overall shielding layer outside the cable core of control cable, signal cable and other cable products, and the outer conductor of coaxial cables.
