Copper foil electromagnetic shielding tape is a purity higher than 99.95% copper foil as a substrate, in the copper foil on one side or both sides coated with pressure-sensitive adhesive and other adhesives made of pressure-sensitive adhesive, divided into ordinary pressure-sensitive adhesive (non-conductive) and conductive acrylic pressure-sensitive adhesive and other types. Copper foil electromagnetic shielding tape is usually presented as a copper-colored tape, the color is more bright, tape surface smooth and flat. It has excellent electromagnetic shielding performance of the special tape, designed for electronic equipment and electrical systems to provide reliable protection against electromagnetic interference. It is made of advanced materials and processes, which can effectively block or attenuate the propagation of electromagnetic waves, ensuring the normal operation of equipment and the clear transmission of signals.
