High-Temperature Aerogel Insulation Boards
The high-temperature aerogel insulation boards from Alfa Chemistry are designed for the most challenging thermal conditions, providing advanced insulation solutions based on nanoporous silica (SiO2) aerogel. These rigid insulation boards are reinforced with inorganic fibers, delivering ultra-low thermal conductivity, mechanical strength, and long-term durability across a wide temperature range from room temperature to 1500°C.
The aerogel's core structure, characterized by nanoscale pores and high specific surface area, disrupts heat transfer mechanisms (conduction, convection, and radiation), making these materials among the most effective thermal insulators available on the market. The robust board format further allows for their application in scenarios requiring mechanical strength, flame resistance, and dimensional stability.

Key Features & Advantages
Superior high-temperature insulation
Silicon dioxide aerogel matrix has a thermal conductivity as low as 0.020 W/m-K at 25°C, providing superior insulation even at extreme operating temperatures of up to 1500°C. The thermal conductivity is as low as 0.020 W/m-K at 25°C.
Space-saving, lightweight design
Thanks to its ultra-low thermal conductivity, the thickness of the insulation can be reduced to one-fifth or one-half that of conventional materials. This not only saves valuable installation space but also minimizes transportation, storage and handling costs.
Excellent hydrophobicity and breathability
These panels have a surface hydrophobicity of ≥99%, which effectively prevents moisture absorption even in situations of high humidity or intermittent water exposure. This ensures that thermal insulation properties remain stable over time and do not deteriorate due to water absorption. At the same time, its inherent porosity maintains excellent air permeability, preventing condensation problems in closed systems.
Superior fire safety
Rated as A1 or A-rated flame retardant, these panels will not burn, release toxic fumes, or contribute to the spread of fire.
Long service life and mechanical durability
These insulation panels have excellent compressive strength and elastic recovery properties. They can withstand mechanical vibration, thermal cycling and handling without structural collapse.
Environmentally friendly and non-toxic
The aerogel panels are free from hazardous substances such as asbestos, benzene and formaldehyde. These materials are non-toxic throughout their life cycle.
Applications
- Construction & Building Envelope: Integrated insulation panels for energy-efficient buildings, especially for applications requiring thin-profile, fire-resistant insulation layers.
- Industrial Equipment: Insulation for medium and high-temperature pipelines, kilns, heaters, and reactors to reduce operational heat loss.
- Furnace Linings: High-performance linings for industrial furnaces operating at 1300–1500 °C, including those used in metallurgy, ceramics, and semiconductor production.
- Aerospace & Defense: Thermal protection for specialized military enclosures and aerospace modules subjected to intense heat and mechanical shock.
- Specialty Enclosures: Insulated housings for thermal batteries, incinerators, and energy storage systems.

FAQs
1. Can these boards be cut to fit specific shapes or dimensions on site?
Yes. The aerogel boards are rigid but can be precisely cut using standard insulation tools to fit complex geometries and surface contours.
2. Are these products suitable for outdoor use?
While hydrophobic, the boards should be mechanically protected if used in outdoor applications where they may be exposed to physical damage or UV radiation over long periods.
3. What is the difference between the 650°C, 1300°C, and 1500°C variants?
They differ in thermal resistance, with each variant optimized for a different maximum service temperature. The higher-temperature versions also have slightly adjusted mechanical properties to withstand more extreme environments.
4. Are these boards compatible with adhesives or mechanical fasteners?
Yes. They can be installed using industrial-grade adhesives, mechanical anchors, or integrated into composite panel systems.
5. Do these boards contain any respirable crystalline silica or hazardous particles?
No. Alfa Chemistry's aerogel boards are composed of amorphous silica and bonded inorganic fibers, and do not pose airborne particulate hazards under normal use.
6. How do these compare to conventional ceramic fiber insulation?
Aerogel boards offer significantly lower thermal conductivity, thinner insulation layers, better hydrophobicity, and longer service life compared to traditional ceramic fiber materials.
7. Are the boards recyclable or reusable?
They are not currently recyclable but are safe for landfill disposal. Reuse is possible if the material remains structurally intact after de-installation.
