The silica aerogel paste AFH series for fiber/blanket application is a sole technology developed by Tec with high end silica aerogel insulation material retaining water repellant(hydrophobic), fire proof and thermal insulation performance. This ready to use product can be applied with fiber/blanket to manufacture high end aerogel-fiber composites.

The AFH series can be applied depending on the customer’s taste for various application. It can be coated on the surface of fiber/blanket to manufacture sandwich panel, impregnate partially or completely to manufacture partially or fully hydrophobic fiber/blanket with significant upgrade in thermal insulation performance( lower value of thermal conductivity TC).

<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.
