Aerogel Thermal Insulation Film (AG-Film)

AG-Film is a thin-film nano thermal insulation material prepared by a fine coating process, applying aerogel water-based slurry onto a variety of functional optional substrates. It targets thermal management problems of precision industrial products in small spaces – heat insulation, heat distribution, and directional heat conduction – protecting weakly heat-resistant components and thereby improving the comfort and service life of electronic products. Thermal conductivity is 0.018-0.025 W/(m·K), film thickness is customizable from 100 to 500 μm, and the material is RoHS compliant. Substrate choice can be matched to the application’s mechanical and temperature needs.

Typical applications listed by the manufacturer are mobile phones, electronic tablets, smart watches, laptops, TVs, and projectors – compact devices where heat must be managed within tight stack-ups. AG-Film protects heat-sensitive components such as displays and batteries from nearby heat sources, and it is easy to die-cut and to composite with heat-dissipation films to build a more complete thermal solution combining insulation and spreading. Its application temperature range of -40 to 120°C covers normal consumer-electronics operating conditions. For positions outside this window, discuss substrate options with the factory during technical review.

AG-Film thickness is customizable across 100-500 μm (0.1-0.5 mm), letting designers match the insulation layer to the available gap. The fine coating process supports precise thickness control, and the film die-cuts cleanly for component-level parts. When specifying, note that the published parameters represent typical test values – the manufacturer’s user notice states that the company guarantees conformance to the product model rather than to each listed value. For gap-critical designs, agree on thickness tolerances during sampling and confirm them in the current TDS or specification agreement before releasing the design to production.

The published parameter table lists a dielectric strength of ≥4 kV/mm and a volume resistivity of ≥1.0×10¹³ Ω·cm, so AG-Film serves as both a thermal barrier and an electrical insulating layer inside compact assemblies. This dual function is valuable where a heat source sits close to conductive housings or circuitry. These are typical values per the manufacturer’s user notice, so for safety-relevant insulation positions, confirm the figures in the current TDS and validate on the final stack-up. Storage guidance is to keep the material tightly sealed in a cool, dry place to preserve coating quality until use.

Yes – the manufacturer explicitly notes that AG-Film is easy to die-cut and to composite with heat-dissipation film to obtain a better thermal solution. In practice this means pairing the insulation layer (to block heat flow toward sensitive parts) with a spreading layer (to move heat laterally toward safe dissipation areas) in one laminated stack. Buyers can discuss composite constructions, substrate selection, and die-cut formats with the factory based on drawings. Note the manufacturer’s user notice: because each application is unique, the material must be tested before use to confirm suitability for your specific design.
