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.
Advantages of Aluminum Foil Mylar
EMI/Static Protection: The conductivity of the aluminum layer eliminates electromagnetic interference (EMI), with a shielding attenuation of 70–80dB in the 1–100MHz frequency band, effectively isolating electromagnetic waves from interfering with equipment and harming the human body.
Static Discharge: When grounded, it can quickly release static electricity, protecting precision electronic components (such as PC motherboards and display screens).
Excellent Physical Properties: Strong adhesion, good mechanical stability, not easy to wrinkle or tear. Waterproof, oil-resistant, and excellent in anti-oxidation performance.
Processing Economy: Supports secondary processing such as slitting, stamping, and custom printing.
Safety and Environmental Protection: Pure water-based coating, no VOC residues, non-toxic and harmless.
Applications of Aluminum Foil Mylar
Shielding Layer Coating: Used in communication cables, coaxial cables, network cables, etc., to prevent signal transmission from being affected by electromagnetic interference.
High-Frequency Wires: Winged aluminum foil mylar is the designated material by associations for high-definition cables such as HDMI and DP, providing an integrated solution for shielding and insulation.
Pasted on the internal gaps of laptops, mobile phones, and monitors to suppress EMI leakage (such as FPC cables, transformers).
Covers precision components of PC boards to prevent current interference.
Sealing the joints of refrigerator/air conditioner pipelines to improve thermal insulation performance.
Industrial air ducts (such as aluminum foil telescopic air ducts) are high-temperature resistant and anti-scouring.
High-frequency transmission isolation for plasma TVs and radio frequency equipment.
Fire-proof places and areas with environmental protection requirements such as food workshops.

The alcohol-resistant series of black conductive fabrics are made by coating the surface of polyester fibers with metals such as copper and nickel, followed by treating a single surface with a black water-based graphene electromagnetic shielding coating. (1) The combination of copper and nickel provides excellent conductivity. (2) The inherent conductive properties 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 polymer coating is resistant to some solvents like alcohol, which can meet special process requirements. (4) The blackening treatment also has properties such as light shielding, oxidation resistance, corrosion resistance, and fingerprint resistance.

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.

The 30-micron wear-resistant black conductive fabric is a high-performance composite material. It uses polyester fiber as the base material, with copper-nickel alloy coated on both sides to provide basic conductivity (surface resistance ≤ 0.05Ω), and a black water-based graphene coating applied on one side. Its core structure consists of a black wear-resistant surface (matte black) paired with a silver-gray conductive surface, offering double-sided conductive functionality. The actually measured thickness of the product is 33-34μm, featuring excellent conductive performance. Its matte black surface presents a low-gloss effect (glossiness 3.2-3.4gs) with stable color (color difference values 25.74/0.05/0.12), and special emphasis is placed on its wear-resistant property. This conductive fabric is manufactured using a pure water-based environmental protection coating process, ensuring no VOC residues and meeting safety and environmental protection requirements. The product has a width of 1100±20mm, which can be directly die-cut or laminated with adhesive tape for easy integration and application. It is suitable for electronic application scenarios such as electromagnetic shielding and grounding that require high conductivity, wear resistance and environmental protection.
