How it Works

Aerogel yarn is developed by grinding silica aerogel into superfine powder and then combining it with polyester. This process integrates the unique properties of aerogel, such as low thermal conductivity and lightweight, with the versatility and strength of polyester. The resulting yarn retains the nanoporous structure of aerogel, filled with still air, which significantly enhances its thermal insulation performance while maintaining flexibility and durability suitable for various textile applications.

Featured

Aerogels have very strong thermal insulation properties, low thermal conductivity, and can resist temperatures of over a thousand degrees. They were first used in NASA’s space suits and are widely used in aerospace thermal insulation layers.

Ultra Light

Aerogel thermal polyester yarn is extremely lightweight, with a density as low as 0.003g/cm³, making it ideal for applications where weight is a critical factor.

Soft and Smooth

The extremely low density of aerogel fiber (as low as 0.003g/cm³) makes it feel light and soft to the touch, adding to its comfort when used in textiles.

Thermal Insulation

Aerogel yarn has a very low thermal conductivity (0.017-0.020W/M.K), making it an excellent insulator.

Aerogel Yarn Applications

Aerogel yarn can be applied to storm jackets, mountaineering clothes, warm gloves, warm shoes and insoles, hats, waistcoats, sleeping bags, tents, yurts, and more. Because of its low thermal conductivity, lightweight, breathable, and hydrophobic characteristics, can provide efficient thermal insulation performance. If you find Lightweight high-performance insulation for alpine conditions, you could choose the aerogel heating yarn.
