Cenospheres Specifications
Cenosphere is lightweight,inter,hollow sphere comprising largely of Silica and Alumina and filled with air and/or gases. Cenospheres are naturally occuring by-products of the burning process at coal-fired power plants.Most of the properties of Censospheres are same as manufactured hollow-sphere products.

Color: Offwhite Gray
Benefits: Reduced raw materials cost,improve flowability,reduced resin deman,improved insualtion values.Resistant to absorption,reduced end product weight. The spherical shape of Cenospheres improves floability in most applications and provides a more even distribution of the filler material. The natural properties of Censosphere are easy to handle and provide a low surface area-to-volume ratio. Due to their inert properties they are not affected by solvents,water,acids or alkalis. Cenospheres are 75% lighter than other minerals currently used as a filler or extender and are 30% lighter than most resins.
