Ceramic Fiber Aerogel Board (AG80B)

AG80B is a rigid, high-temperature insulation board for duties where mechanical strength matters as much as thermal performance: construction applications, ceramic kilns, steel annealing lines, and other industrial furnaces, plus firefighting equipment and facilities, special military equipment insulation, solar thermal collectors, and applications with special insulation requirements. Its smooth, flat surface suits flat hot-face or back-up lining positions. With a long-term operating temperature up to 850°C, it targets services where flexible blankets cannot provide the required structural integrity or surface flatness.

AG80B has a published long-term operating temperature of up to 850°C, with an applicable temperature range of -50 to 1000°C in the specification table. Thermal conductivity at 25°C is 0.017-0.023 W/(m·K), rising through the published curve: 0.033 at 300°C, 0.041 at 400°C, 0.06 at 500°C, 0.08 at 600°C, 0.11 at 700°C, and 0.137 W/(m·K) at 800°C. Thickness design should use the conductivity at the actual mean temperature of the insulation layer rather than the ambient-temperature figure.

AG80B is supplied as a rigid board in a standard size of 885 x 500 mm, with a standard thickness of 10 mm or customized thicknesses on request. Published density is 300 kg/m3, and chloride ion content is 0.001%, which is relevant for stainless steel equipment where chloride stress corrosion is a concern. Because the board is rigid and flat, it cannot be bent to fit curved shells; for pipes or vessels, a flexible aerogel blanket format should be considered. Confirm custom thickness capability and tolerances in the current TDS before ordering.

The published performance claim is that AG80B achieves equivalent insulation results at only one-fourth the thickness of traditional materials, owing to its ultra-low thermal conductivity. At the same time, the board offers strong structural integrity with excellent tensile and compressive strength among lightweight insulation materials, plus excellent resistance to flame impact from its raw materials and production process. This combination suits confined furnace linings and hot-face back-up layers. For load-bearing or abrasion-exposed positions, confirm mechanical design values with our engineers, as detailed strength data is not published on this page.

AG80B boards should be handled as rigid, brittle-matrix insulation: support boards during transport and lifting, avoid point impacts on edges and corners, and cut with appropriate sharp tooling on a flat bench. The smooth surface is intended for flat installation positions; boards must be fully supported by the furnace wall, casing, or anchoring system designed by the project engineer. The product is an insulation layer, not a structural hot-face lining, so exposure to direct flame impingement, mechanical abrasion, or chemical attack should be reviewed against the actual service conditions before specification.
