Aerogel+ Products All You Need for Thermal Insulation
Aerogel Insulation Material | China | Top Leading| China | Top Leading
AG-TT Aerogel thermal insulation cotton is made from aerogel staple fibers via a special processing technique. It possesses the excellent thermal insulation properties of aerogel, and can be directly filled into items like military uniforms, thermal coats, jackets, quilts and pillows. It outperforms ordinary fiber insulation cotton in insulation performance, and retains its shape even after repeated washes. This material not only enhances the mechanical properties of the aerogel itself, but also endows the fibers with even better thermal insulation performance.
Mechanical Properties
Heat Insulation And Heat Preservation
AG-TT Aerogel Thermal Cotton is a high-performance filling material combining aerogel-enhanced fibers with polyester structure, designed for thermal apparel and home textile applications.
It offers significantly improved insulation compared to conventional fiberfill, while maintaining excellent softness, resilience, and long-term durability. With thermal performance approaching down at similar weight, AG-TT is an ideal alternative for brands seeking lightweight, washable, and cost-effective insulation solutions.
By integrating aerogel into polyester fibers, AG-TT effectively reduces heat transfer and improves insulation efficiency.
Thermal performance close to down at the same gram weight
Higher insulation efficiency than standard polyester filling
Suitable for lightweight yet warm product designs
Soft, Fluffy & Comfortable
AG-TT is engineered to deliver a balance between warmth and comfort:
Soft and skin-friendly texture
Excellent loft and fluffiness
Better compression resilience than conventional “silk-like” cotton
This ensures a comfortable wearing experience in apparel and soft-touch performance in home textiles.
Traditional filling materials often lose shape and insulation after repeated washing.
AG-TT is designed to overcome this issue with a stable fiber structure:
Maintains loft and shape after 40+ wash cycles
No clumping or hardening
Consistent thermal performance over time
This makes it especially suitable for frequently washed products.
AG-TT meets strict international textile safety standards:
OEKO-TEX® Standard 100 certified
RSL (Restricted Substances List) compliant
Non-toxic and safe for direct skin contact
Suitable for apparel and home textile applications.
We offer a wide range of customizable options to match different product requirements:
Gram weight: 20–200 g/m²
Thermal performance: 0.84–3.84 Clo
Thickness: customizable
Available in bulk for direct filling into finished products or further processing.
AG-TT aerogel insulation cotton is suitable for a wide range of thermal products:
Jackets and coats
Sportswear and outdoor clothing
Workwear and uniforms
Mountaineering jackets
Cold-weather gear
Quilts and duvets
Pillows
Thermal bedding
Hats, gloves, scarves
Other cold-weather accessories

Aerogel cotton, when used in pillows, can stabilize head temperature and improve sleep comfort without increasing thickness or stuffiness.
Aerogel cotton is used inside tents to prevent water absorption and clumping with stable thermal insulation performance, meeting the requirements of extreme outdoor environments.
Aerogel cotton, when used as filling for down jackets, provides better insulation and is less prone to absorbing water and clumping.

The decrease is almost negligible! Tests show that the Clo value of aerogel insulation cotton decreases by only 0.36%-3.89% after washing, and some models even show a slight increase in insulation value after washing, while the insulation performance of 80% and 90% down bags decreases by 3.94%-14.59% after washing.
Our AG-TT series aerogel cotton has obtained Oeko-Tex Standard 100 certification and has successfully passed the RSL safety test, using safe and harmless substances.
Currently, the highest Clo value of our AG-TT series aerogel insulation cotton is 3.84 Clo, corresponding to model AG-TT200, with a weight of 200g/㎡ and a thickness of 36mm.
Weight is determined by a five-point sampling method with a sampling area of 50cm×50cm; thickness is measured under a standard pressure of 0.02Kpa with an effective pressure-bearing area of 30cm×30cm.
At the same grammage, aerogel cotton delivers excellent thermal performance: 60g aerogel insulation cotton (Clo 1.52) outperforms 60g 3M Thinsulate G-Series (Clo approx. 1.30), and 100g aerogel insulation cotton (Clo 2.45) is close to 100g 3M Thinsulate G-Series (Clo 2.5).
At the same grammage, the thermal insulation value of aerogel insulation cotton far exceeds that of silk-like cotton: 20g aerogel insulation cotton (Clo 0.84) vs. silk-like cotton (Clo 0.65); 80g aerogel insulation cotton (Clo 1.94) vs. silk-like cotton (Clo 1.65); 200g aerogel insulation cotton (Clo 3.84) vs. silk-like cotton (Clo 2.81).
The thermal performance of 40g aerogel insulation cotton (Clo 1.26) is superior to 20g 80% down (Clo 1.399, dropping to 1.257 after washing). Moreover, its thermal insulation performance remains almost unchanged after washing, whereas 80% down experiences a significant drop of 10.15% in thermal insulation post-washing.
Suitable for military uniforms, thermal outerwear, windbreakers, sportswear, work clothes, thermal underwear, jackets, hand warmers, and neck warming accessories, etc.
