05. Application Reference– Blanket subsequent processing
<Linear cut of molded blanket>By combining silica aerogel and glass fiber, depending upon the degree of impregnation physical features like flexibility, strength, molding and chemical feature like hydrophobic nature can be controlled. Different types of fiber/ blankets can be selected for manufacturing products according to the range of applying temperature and nature of application site.
<Surface treatment of aerogel blanket>After molding and processing, product's surface treatment can be done depending upon the application requirement such as aluminum casing or taping the surface as shown in the picture. In case of no special surface treatment required, due to physical‐chemical properties of the product the basic features such as water repellant, anti‐corrosion, strength can be achieved.
Easy installation and excellent molding product. Excellent insulation performance, water repellant performance makes it better than glass fiber in terms of water absorption. Non‐dusty product, safe to human compared to other glass fiber products.

06. Performance Test – Condensation test
<While test> <After 24 hours of test>
<Condensation test for Aerogel paste-fiber composite>
The picture shows the condensation condition of aerogel‐fiber composite after 24 hours condensed continuously at ‐14.6 degree Celsius. The steel surface without being covered by aerogel fiber composite has condensed below zero and ice is formed on the surface whereas the aerogel‐fiber composite surface is not affected at all. This result is obtained due to the thermal insulation performance as well as excellent hydrophobic performance of the surface of aerogel‐fiber composite. This combined feature makes it applicable at lower temperatures also.
