SEPPE Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.4-0.8 g/cm�³, which gives them a great buoyancy. Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.
