1. What is Silica Aerogel Felt?

Silica Aerogel Felt is a flexible insulation material consisting of silica aerogel integrated into a fibrous support structure. It provides very low thermal conductivity while remaining flexible and easy to install.

2. What is Silica Aerogel Felt used for?

Silica aerogel felt is used for industrial insulation, cryogenic systems, pipelines, tanks, battery thermal management, aerospace systems, chemical processing equipment, high-temperature equipment, and energy applications.

3. Why does silica aerogel provide excellent insulation?

Silica aerogel contains a highly porous structure that limits heat transfer through the material, resulting in extremely low thermal conductivity compared with many conventional insulation materials.

4. Can Silica Aerogel Felt withstand high temperatures?

Yes. High-temperature grades can operate at temperatures reaching several hundred degrees Celsius and, for specialized ceramic-fiber grades, approximately 1,000°C, depending on the product construction and application.

5. Is Silica Aerogel Felt flexible?

Yes. Unlike rigid aerogel monoliths, aerogel felt and blanket products are flexible and conformable, making them suitable for pipes, tanks, curved surfaces, and irregular geometries.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting thermal conductivity, density, thickness, dimensions, temperature rating, hydrophobicity, and other applicable product specifications.
