NOVELTY - Multilayer composite heat-conducting shielding adhesive tape comprises a release film layer, a first heat-conducting pressure-sensitive adhesive layer, a graphene layer, a second heat-conducting pressure-sensitive adhesive layer and a copper foil layer including copper foil with multi convex structure on the surface and a radiating conductive ink coated on the surface of the copper foil, and the convex height of the convex structure is 300-1500 nm. USE - Used as multilayer composite heat-conducting shielding adhesive tape. ADVANTAGE - The adhesive tape: can contact the surface area of the copper foil, and matched with the radiating conductive ink on the surface of the copper foil, namely reduce the thermal resistance of the surface of the copper foil, reducing the resistance of the surface of the copper foil, and improve the radiating efficiency and conductive performance of the copper foil layer.
