CENOSPHERE

75um cenosphere spec.: Specific Gravity: 0.5 -- 0.75g/cc Bulk density : 0.250.33 g/cc Sinker : <10%; Moisture: < 1% 75um>98%

A cenosphere is a lightweight, inert, hollow sphere comprising of largely of silica and alumina and filled with air and / or gas

75um cenosphere specification:

Specific Gravity: 0.5 -- 0.75g/cc

Bulk density : 0.250.33 g/cc

Sinker : < 10%

Moisture :  < 1%

75um passing > 98%

Benefits: 1) Reduced raw materials cost 2) Improved flowability 3) Reduced resin demand 4) Improved insulation values resistant to resin absorption 5) Reduced end product weight Manufacturing Benefit: The spherical shape of cenospheres improves flowability in most applications and provides a more even distribution of the filler material. The natural properties of cenospheres make it possible to use them either in dry or wet slurry form. Cenospheres 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 percent lighter than most resins.
