Aerogel Board Insulation Panels (AG65B)

AG65B is a rigid insulation board for flat-surface duties: insulation and thermal protection of industrial heat distribution networks, medium- to high-temperature industrial equipment and furnaces, steam turbine thermal insulation, and pipeline insulation and thermal protection where flat panels fit. Typical examples include ceramic roller kilns. With a maximum long-term operating temperature of 650°C and thermal conductivity around 0.02 W/(m·K) at room temperature, it suits confined spaces; the page also notes it as a solution for cryogenic applications within its published -50 to 650°C applicable range.

AG65B is made with a glass fiber needle-punched felt base. The felt is immersed in a sol-gel slurry, aged, and then subjected to supercritical extraction to remove organic solvents, leaving nano-porous aerogel uniformly distributed through the fiber matrix. The result is a rigid board with a published density of 250 kg/m3 (the description cites a 250-300 kg/m3 range). The aerogel phase has a porosity of 85-99% with nanopores smaller than the mean free path of air molecules, eliminating convective heat transfer, while the high specific surface area reduces radiative transfer.

As stated on this page, AG65B features a rigid, flat structure that cannot be bent, unlike the flexible AG65. The board form gives a smooth surface and dimensional stability for flat applications such as ceramic roller kiln panels, while the flexible blanket is the appropriate choice for curved surfaces like pipes and storage tanks. Both share the glass fiber felt base and sol-gel aerogel process. Select AG65B where surface flatness, compressive resistance, or self-supporting panels are required; select the flexible format where wrapping and conformance to curvature are needed.

AG65B is supplied as 885 x 500 mm boards, 10 mm thick or customized. Thermal conductivity at 25°C is 0.017-0.023 W/(m·K), with the published curve reading 0.021 at 25°C, 0.023 at 100°C, 0.026 at 200°C, 0.029 at 300°C, 0.033 at 400°C, 0.037 at 500°C, and 0.041 W/(m·K) at 600°C. The applicable temperature range is -50 to 650°C, and chloride ion content is 0.001%. At high temperature, one-third to one-fourth of the thickness of traditional ceramic or glass fiber insulation achieves the same thermal resistance.

Because AG65B is rigid and non-bendable, it must be installed on flat surfaces with full support from the casing, wall, or anchoring system; forcing it onto curved shells will crack the board. Handle panels flat, protect edges and corners from impact, and cut with sharp tooling on a supported bench. The board offers strong structural integrity and excellent tensile and compressive strength for a lightweight insulation material, but it remains an insulation layer rather than a structural component. Expansion allowances, joints, and any hot-face protection are the responsibility of the lining or system designer.
