How it Works？
Hollow-star aerogel fibers feature a distinctive cross-sectional geometry with radiating points forming a star pattern around a central hollow core. This architectural design creates multiple air-trapping chambers along the fiber’s length, fundamentally changing how heat retention occurs within textile structures. Aerogel materials achieve exceptional thermal insulation performance through nanoporous structures with thermal conductivity ranging from 0.014 to 0.020 W/(m·K), where pore sizes remain smaller than the mean free path of gas molecules .
Featured
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 fiber has a very low thermal conductivity (0.017-0.020W/M.K), making it an excellent insulator.
Aerogel Paddings/Fillings Applications
Aerogel paddings/fillings 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, it can provide efficient thermal insulation performance. If you find Lightweight high-performance insulation for alpine conditions, you could choose the aerogel heating paddings.
