The 30μm insulating alcohol-resistant black conductive cloth is made by coating the surface of polyester fibers with metals such as copper and nickel, followed by treating one surface with a black water-based graphene electromagnetic shielding coating. The black insulating surface has an insulation resistance of >10¹⁰Ω and a thickness of 38±3μm. The insulating layer presents a low-matte blue-black color with a glossiness of 0.5 and stable color difference (Lab value: 26.45/-0.17/-1.12). It adopts a purely water-based and environmentally friendly coating (free of VOCs) and features excellent wear resistance and alcohol resistance. It supports direct die-cutting or composite adhesive layer processing, and is suitable for electromagnetic shielding, anti-static protection of precision electronic components, and industrial corrosion-resistant scenarios.

Aluminum foil Mylar is a kind of composite shielding material, which is made by compounding high-purity aluminum foil with PET polyester film (also known as Mylar film) through coating conductive adhesive or hot-melt adhesive. Its structure is usually divided into single-sided, double-sided, hot-melt and winged (butterfly wing) types, with a thickness range of 0.06–0.15mm, and it has both the conductivity of metal and the insulation of polymer materials.

The alcohol-resistant insulating black conductive non-woven fabric is an ultra-thin functional material (which can be as thin as 17 microns) with a conductive non-woven fabric as its base material. It adopts a single-sided conductive design: one side is silver-gray and has conductivity; the other side is low-matte and neutral black, providing excellent insulating performance, and the surface of this black coating is wear-resistant and has good alcohol resistance. The product uses a purely water-based environmental protection coating, with no VOC residues, and features super softness and durability. It is easy to process (can be directly die-cut or glued) and can be personalized and customized. It is an ideal base material for manufacturing high-performance conductive tapes (such as conductive non-woven fabric tapes and conductive double-sided tapes), and is widely used in precision electronic devices that require electromagnetic shielding, grounding, insulation and resistance to cleaning.

The single-sided gray insulating alcohol-resistant conductive cloth uses polyester fiber as the base material, with a copper-nickel metal layer coated on the surface to achieve conductivity, and a low-matte gray water-based graphene insulating coating applied on the outer layer. The insulation surface resistance is greater than 10¹⁰Ω, and it has excellent wear resistance and alcohol resistance. It adopts a VOC-free pure water-based environmental protection process. Its gray coating has stable color difference, and the thickness and performance can be customized. It supports direct die-cutting or composite processing, and is specially used in electromagnetic shielding, anti-static and industrial corrosion-resistant scenarios of precision electronic components that require a specific gray appearance.

The single-insulated series of single-sided black conductive fabric is made by coating the surface of polyester fibers with metals such as copper and nickel, followed by a treatment with a black water-based graphene electromagnetic shielding coating on one surface. (1) The combination of copper and nickel provides excellent electrical conductivity. (2) The inherent conductive property of the graphene electromagnetic shielding coating can greatly enhance the conductivity of the composite material, achieving good shielding effectiveness in the frequency range from 10MHz to 3GHz. (3) The resistance of the polymer insulating coating exceeds 10⁶ Ω, which can meet the requirements of special manufacturing processes. (4) The blackening treatment also has properties such as light shielding, oxidation resistance, corrosion resistance, and fingerprint resistance.
