Film-coated Aerogel Sheet

Film-coated Aerogel Sheet is an insulation sheet made from aerogel blanket through composite processing, with surface lamination such as aluminum foil that makes it waterproof, non-shedding, and vibration-resistant. Minimum thickness can be as low as 1 mm, with 1-2 mm options highlighted, while thermal conductivity stays at 0.017-0.023 W/(m·K) at 25°C – achieving equivalent insulation at roughly one-fourth the thickness of traditional materials. The film coating solves the dusting issue of bare aerogel blanket, so the sheet can be used inside enclosed equipment where particulate contamination is unacceptable.

Typical applications listed by the manufacturer are fire-resistant insulation for power battery packs, insulation and fire protection for high-speed train and automotive carriages, and fire insulation for household appliances, as well as electronic devices. The combination of ultra-thin profile, fire resistance (V0 grade), and a sealed, non-shedding surface suits positions where insulation must survive vibration and possible moisture exposure – for example, between battery cells or modules, around heating elements in appliances, or within vehicle body panels. The applicable temperature range is -50 to 200°C.

Published specifications include: thermal conductivity at 25°C of 0.017-0.023 W/(m·K); applicable temperature of -50 to 200°C; fire resistance grade V0; RoHS environmental certification; insulation impedance above 500 mΩ; stiffness ≥1.9 mN·m; and waterproof construction. Specifications are customized as required – thickness from 1 mm upward, dimensions, and surface film type can be matched to the project. These values give designers a verified starting envelope, but final figures for a customized build should be confirmed in the current TDS or a project specification before design freeze.

Yes. Specifications are customized as required, and the sheet’s 1-2 mm ultra-thin options were developed with space-constrained fire insulation in mind, including power battery packs. Buyers can specify thickness, sheet dimensions, and surface treatment – the description notes processes like aluminum foil lamination that provide waterproofing, moisture resistance, vibration resistance, and non-shedding behavior. Die-cut or shaped parts can be discussed against your pack drawings, and the V0 fire grade and >500 mΩ insulation impedance are relevant inputs for battery safety design. Samples for pack-level testing can be arranged during the sampling stage.

The applicable temperature ceiling is 200°C, so positions seeing higher continuous or instantaneous temperatures need a different construction – discuss alternatives with the factory rather than exceeding the rating. The sheet is semi-rigid by design (stiffness ≥1.9 mN·m), which aids handling but means it is not intended for tight-radius wrapping; use flat or gently curved placements. Customized builds may shift properties slightly from the published table, so confirm lot-specific values in the current TDS. While the film surface blocks dusting, cut edges should be handled per the factory’s guidance to keep the assembly clean.
