Special Fiberglass Aerogel Blanket (AG90)

AG90 is used for thermal insulation on petrochemical pipelines, district heating pipelines, storage tanks, armored vehicles, modular shelters, new energy battery systems, and energy-efficient buildings. Its glass-fiber-reinforced silica aerogel structure combines very low thermal conductivity with a maximum service temperature of 900°C, so it is typically selected where conventional mineral wool or calcium silicate would require several times the thickness. For critical duties involving thermal cycling, vibration, or outdoor exposure, provide your operating envelope so our engineers can confirm thickness and layering against the current TDS.

AG90 consists of silica aerogel integrated with a high-performance glass fiber mat, manufactured through sol-gel technology and supercritical drying. The inorganic glass fiber mat reinforces the inherently brittle aerogel phase, giving the composite adequate mechanical strength and processability while preserving the nanoporous structure responsible for its insulation performance. Published density is 0.15-0.21 g/cm3 (GB/T 34336-2017), compression recovery is at least 90%, and vibration mass loss is no more than 1%, which supports installation on piping and equipment subject to movement.

The published maximum service temperature is 900°C. Thermal conductivity is 0.021 W/(m·K) or less at 25°C (GB/T 10295-2008) and 0.072 W/(m·K) or less at 300°C (GB/T 10294-2008). Because conductivity rises with mean temperature, thickness selection for hot service should be based on the elevated-temperature value rather than the room-temperature figure. If your design point sits above 300°C, contact our engineering team for guidance and confirm all design inputs against the current TDS before finalizing heat-loss or surface-temperature calculations.

AG90 is produced in 3 mm, 6 mm, and 10 mm thicknesses with a standard width of 1500 mm; the specification table lists both thickness and width as customizable. This allows project orders to be matched to pipe OD, tank geometry, or enclosure panel sizes, and multi-layer installations can be built up where higher thermal resistance is required. Dimensional tolerances and roll lengths are not published on this page, so please confirm tolerance, length, and cutting allowance in the current TDS or your purchase specification before placing production orders.

Installers should wear a dust mask and rubber gloves, keep the blanket clean and dry, and avoid contact with oil, water, or other organic solvents. Cut with sharp tools to prevent cracking or delamination along the cut line. AG90 is an inorganic, low-organic-content material with a Class A2 fire rating (GB 8624-2012) and moisture absorption of 5% or less (GB/T 5480-2017), so it is inherently non-combustible and hydrophobic. It remains a non-structural insulation layer: outer jacketing, banding, and weather protection must be designed by the system engineer.
