Aerogel Insulation Sponge (AG-Sponge)

AG-Sponge is a flexible aerogel insulation material with low density (110±20 kg/m³) and low thermal conductivity of ≤0.018 W/(m·K) at room temperature, tested per GB/T 10295-2008. It carries a V-0 flame-retardant grade (UL-94), complies with RoHS and REACH prohibited-substance requirements, and offers strong acoustic performance: a sound absorption coefficient of 0.92 at 2000 Hz and a noise reduction coefficient of NRC 0.90. Permanent compression set is ≤5% per GB/T 6669-2008. The material is soft, thin, and easy to cut, supporting convenient post-processing into project-specific shapes.

AG-Sponge is positioned for civil, industrial, construction, transportation, aviation, military, daily chemical, and electronic information fields – especially environments requiring flame retardancy, high-temperature resistance, and low-frequency noise absorption together. Its operating temperature range of -180 to 200°C (per GB/T 34336-2017) covers cryogenic-leaning through elevated-temperature service. Typical uses combine thermal insulation with acoustic damping, such as equipment enclosures, transportation interiors, and electronic assemblies where both heat control and noise reduction are specified. The V-0 flame rating and RoHS/REACH compliance support use in regulated products and export markets.

Standard thickness runs from 0.5 to 4 mm with customization available, and the standard width is a 1200 mm wide roll, with customized widths also possible. The material can be coated on one or both sides and supplied with double-sided adhesive on the back, customized as needed – useful when the sponge must be fixed inside an enclosure without additional fastening. Because it is soft and easy to cut, it converts readily into die-cut parts, strips, or laminated composites. Buyers can submit drawings so the factory can confirm achievable tolerances and propose the most material-efficient converting format for the application.

The manufacturer lists several precautions. Tensile strength is not high, so the material can tear or break if improperly stressed – avoid stretching during installation. It has some elasticity and rebounds under pressure, but compression beyond the limit causes permanent deformation; the published permanent compression set is ≤5% under standard test conditions, which should not be confused with overload behavior. The surface may show slight powdering, so sealed or coated constructions are advisable where particulate control matters. Store and handle rolls to avoid creasing, and validate compression loading in the actual assembly before finalizing gap designs.

The published parameter table states RoHS and REACH compliance for prohibited substances, and a V-0 flame-retardant grade under UL-94 – both relevant for products sold into regulated markets. Thermal conductivity is tested to GB/T 10295-2008, density to GB/T 6343-2009, and operating temperature to GB/T 34336-2017, giving traceable test standards for each key property. For projects requiring documentation, the factory can provide current test reports or certificates on request. As with any material qualification, buyers should verify that the specific lot’s documentation matches their compliance checklist before releasing the material to production.
