Buyers who reach out about an aerogel insulation sheet for electronics and equipment applications are almost never insulation specialists — they're component engineers, battery pack designers, or contract manufacturers who hit a thermal problem after their product's form factor was already locked in. The device got thinner, the power density went up, and the insulation layer they'd been using no longer fits inside the enclosure without a redesign.
Electrical and electronic products keep pursuing two goals that pull against each other: thinner form factors and better thermal control. A standard foam or felt insulation layer thick enough to manage heat properly often no longer fits in the available cavity — this is the "homogenizing problem in narrow space" that most inquiries for an aerogel insulation sheet start from. The buyer isn't asking "what is aerogel," they're asking "can you get me the same thermal performance in a quarter of the thickness I'm currently using."
Foam and rubber insulation — reaches the needed thickness fine, but at 3-6x the material bulk of aerogel for the same thermal result, which often no longer fits the enclosure at all.
Mica sheet, long used in electronics and battery packs for its insulating properties, doesn't match aerogel's combination of low thermal conductivity and minimal thickness, and is heavier for the same coverage area.
General-purpose insulation felt typically isn't rated to the fire-safety class electronics and battery manufacturers are increasingly required to meet.
Our thinnest production capability reaches 0.5mm, purpose-built for the cavity constraints of modern electrical and electronic assemblies. Key specification points buyers check against their own datasheet requirements:
Thermal conductivity of 0.016 W/(m·K) — delivering 3-6x the thermal insulation effect of traditional materials at a fraction of the thickness
Meets the National Aerogel Standard, Level S — the compliance benchmark procurement and quality teams ask for by name
Thickness as low as 1/4 that of traditional insulation materials, freeing up internal volume without a product redesign
Fire rating A, inorganic and non-combustible — relevant wherever the equipment is subject to fire-safety certification
Inorganic and environmentally compliant composition, supporting RoHS-adjacent material declarations buyers increasingly need from suppliers
For battery pack applications specifically, our Aerogel Sheet for New Energy Battery is reinforced with glass or ceramic fiber and laminated with PET foil, purpose-built as a cell-to-cell thermal barrier to contain thermal runaway before it propagates across the pack — this is the most common reason EV and energy-storage buyers come looking for an aerogel thermal barrier in the first place.
Sourcing an aerogel insulation sheet for a production line is rarely a one-SKU purchase — it's an integration project. For electronics and equipment customers, our OEM support typically covers:
Custom die-cutting to your enclosure geometry, rather than shipping standard rolls for in-house cutting
Lamination options (PET foil, adhesive backing) so the material integrates directly into your assembly line without an extra bonding step
Thickness tuning below and above the 0.5mm baseline to match your specific cavity, not just standard catalog gauges
Private-label packaging for distributors and contract manufacturers reselling under their own brand
Our full customization scope — shapes, densities, hydrophobic/hydrophilic formulation, reinforcement fiber type — is detailed on our Service and OEM,the summary above is specific to what electronics and equipment buyers actually request
Nano Tech has manufactured silica aerogel and its composites since 2004, and drafted the national standard this Level S rating is measured against — so when a buyer asks for compliance documentation, it isn't outsourced or approximated, it's built into how we test every batch. Our in-house R&D team runs high-precision thermal conductivity testing on every production run, and with 8,000,000 square meters of annual output capacity, we support both prototype-quantity orders for new product development and the recurring volume electronics and battery manufacturers need once a design goes into mass production.
If your product's thermal problem is being caused by a space constraint rather than a lack of insulation options, our team can match a thickness and fire rating to your specific enclosure.Contact us to request samples of our aerogel insulation sheet or a technical spec sheet for your project
