Single-sided black insulating aluminum foil is a composite functional material based on an ultra-thin metal substrate. Its structural design features a single side coated with a black insulating layer, while the other side retains the original metallic color. This material combines multiple properties: the black insulating side provides high resistivity to block current conduction, preventing circuit short circuits, and at the same time reduces optical reflection; the metallic side maintains excellent electrical conductivity and thermal conductivity. Through a precision coating process, an ultra-thin integrated structure is achieved, which exhibits excellent performance in terms of flexibility, processability (supporting die-cutting/laser cutting), and environmental adaptability (temperature resistance from -40℃ to 400℃, flame retardancy meeting UL94V0 standard, and compliance with RoHS). It provides a synergistic solution for electromagnetic shielding, insulation protection, and thermal management in electronic devices.

Single-sided black conductive aluminum foil is a composite functional material based on metal copper foil, with an ingenious structural design: one side retains the metallic primary color, while the other side is coated with a special black conductive layer. This material usually adopts advanced roll-to-roll sputtering technology or nano-coating technology to realize functional coatings on ultra-thin metal substrates. In terms of thickness control, the material has broken through key technical bottlenecks, and the aluminum foil can be customized to specifications of less than 35μm. At the same time, through precision manufacturing processes, the material maintains excellent physical properties even in an ultra-thin state. In terms of surface characteristics, the material has double-sided conductivity. Among them, the surface resistance of the black side is strictly controlled at an extremely low level of ≤0.05Ω, ensuring excellent current conduction and electromagnetic shielding efficiency. The metallic primary color side shows high gloss, and the color difference value can be adjusted through customized production processes to meet the strict requirements of various high-end electronic devices for appearance aesthetics. The overall structural design of the material is scientific and reasonable, usually including three functional layers: the metal substrate layer (providing mechanical support and basic thermal conductivity), the black conductive layer (realizing EMI shielding and thermal radiation), and the optional adhesive layer (facilitating installation and fixation). The multi-layer structure works synergistically to endow the material with comprehensive performance advantages.
