This product is an aqueous solution of nano-graphene material after special dispersion technology, which makes reasonable use of the conductivity of nano-graphene material, electromagnetic and electric properties. Shielding, super-high thermal conductivity and high thermal conductivity and shielding combined with rolled copper and platinum, which are laminated on the surface of copper and platinum by a special process, increase the shielding performance. The heat fusion ratio of the material, the reasonable use of the composite material thermal conductivity, good electromagnetic shielding effect, the graphene and non-ferrous metal tensile Perfect combination of sexual function. Used for plasma liquid crystal display, computer and peripheral equipment, mobile phones, shielded cable and other electronic products, thermal shielding.
