Why Choose Us
The Supreme Advantage

Cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and is filled with air or inert gas. It is typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and the density is about 0.4–0.8 g/cm3. Cenospheres are small, high strength, extremely lightweight, free flowing, non porous, hollow ceramic spheres.

The hollow ceramic glass bubble shape of the Microsphere results in a variety of uses other than simply being used as a light-weight filler. Cenospheres are used as a Filler to replace minerals and resins where the benefits may be as diverse as weight reduction, improved thermal insulation, reduced shrinkage, improved fire resistance or simply easier application.

Supreme Cenosphere has several predefined product specifications to cater the needs of various industries. Needless to say, our range of products is not limited and with a strong team of in house experts, we can tailor the products to meet the most stringent of your needs.
