Aerogel Felt (GB Standard)
Overview
National Standard Aerogel Felt is a cutting-edge thermal insulation material made from silica aerogel, one of the lightest solid materials known. It combines the properties of aerogels with the flexibility of a felt structure, making it highly versatile for various industrial and commercial applications. The material is designed to meet stringent national standards for thermal performance and safety. Its unique nanostructure provides exceptional insulation with minimal thickness, making it ideal for space-constrained applications.
Physical and Chemical Properties
Aerogel felt exhibits ultra-low thermal conductivity, typically ranging from 0.015 to 0.025 W/m·K, which outperforms traditional insulation materials. Its porous structure, composed of over 90% air, contributes to its lightweight nature and superior insulating capabilities. The material is hydrophobic, meaning it repels water while maintaining its insulating properties even in humid environments. It is also fire-resistant, withstanding temperatures up to 650°C without significant degradation.
Main Applications
In industrial settings, aerogel felt is used for insulating pipelines, tanks, and equipment in oil and gas, chemical, and power plants. Its ability to reduce heat loss and improve energy efficiency makes it a preferred choice for high-temperature applications. In construction, it is employed in building envelopes, roofs, and walls to enhance thermal performance without adding bulk. The aerospace industry utilizes aerogel felt for thermal protection in spacecraft and aircraft due to its lightweight and high-performance characteristics.
Safety and Storage
While aerogel felt is non-toxic, precautions should be taken to minimize dust generation during handling. Proper ventilation and protective equipment, such as masks and gloves, are recommended when cutting or installing the material. Storage should be in a dry, cool environment to preserve its properties. Avoid exposure to direct sunlight or extreme temperatures, as prolonged exposure may degrade the material over time.
B2B Procurement Guide
When procuring aerogel felt, verify the supplier's compliance with national standards and request test reports for thermal conductivity, fire resistance, and hydrophobicity. Ensure the product meets the specific requirements of your application, such as temperature range and mechanical strength. Consider factors like thickness, density, and roll size to match project needs. Bulk purchases may offer cost savings, but ensure proper storage conditions to maintain material integrity before use.
