AGF-AAL Aluminum Foil Composite Aerogel Insulation Film

AGF-AAL composites an aerogel coating with a 20, 30, or 50 μm aluminum foil substrate, in standard total thicknesses of 100±10, 200±20, and 300±20 μm, customizable across 50-400 μm. The aerogel layer’s thermal conductivity is 0.022-0.026 W/(m·K), while the aluminum foil reflects radiant heat and adds tensile and puncture resistance beyond what PET substrates offer – the foil’s tensile strength is ≥100 MPa. The bond between coating and foil is engineered to eliminate powder shedding even under vibration, creating a dual barrier of conductive-aerogel insulation plus radiant reflection in one thin laminate.

AGF-AAL is described as a preferred insulation solution for electronic devices and 3C electronics, with manufacturer-listed applications including wearable devices, smartphones, laptops, tablets, OLED displays, smart TVs, digital cameras, and consumer electronics. The film can be adhered directly to components using pressure-sensitive adhesive. Because aluminum foil combines low density – 2.7 g/cm³, about one-third the weight of copper – with corrosion and oxidation resistance, AGF-AAL suits weight-sensitive assemblies that also need mechanical robustness and a radiant-heat barrier, such as insulation points near batteries, displays, or compact power components inside portable devices.

The specification table lists a temperature resistance range of -40 to 240°C and a continuous operating temperature of -20 to 220°C for AGF-AAL, matching the foil- and graphite-based models and well above PET-based constructions. The aluminum substrate tolerates these temperatures without the softening limits of polymer films, and its corrosion resistance supports long service life. Designs operating continuously near the upper boundary should still be validated on the actual assembly, since adhesive selection and lamination interfaces can set practical limits. Confirm the figures applicable to your lot in the current TDS before finalizing thermal design margins.

AGF-AAL is supplied in rolls with customizable size. Beyond the standard 100, 200, and 300 μm gauges, total thickness can be tailored within 50-400 μm, and the aluminum foil substrate can be specified at 20, 30, or 50 μm depending on the balance of weight, strength, and cost required. The laminate converts into cut shapes for placement on components, and pressure-sensitive adhesive mounting is supported per the product description. Buyers can provide drawings so the factory can confirm tolerances and propose roll or die-cut formats. Evaluation samples and project-specific packaging can be arranged during the sampling stage.

Because the substrate is conductive aluminum foil, the published table lists no dielectric strength rating for AGF-AAL, and the foil face must not bridge live conductors – if electrical isolation is required, plan an insulating layer or confirm the arrangement with the factory. Volume resistivity is published at ≥1.0×10¹³ Ω·cm for the construction, but treat this as a typical value and verify in the current TDS. No UL94 flame rating is published. The foil also reflects radiant heat, which is an advantage in most cases but should be considered in thermal simulation. Store in a dry, room-temperature environment; published shelf life is three years.
