Share Some Knowledge Points About SEPPE Cenosphere

Microspheres have been known for years, but as demand for improved materials and increased functionality from everyday products grows, so too has demand for these strong yet intricate little balls.

SEPPE cenospheres are made from the pulverized fuel ash produced as a waste product from coal-fired power stations. These alumina-silicate balls range in size from 5 to 500 µm and are usually hollow, giving them a very low-density. This makes them very useful for any number of filler purposes for construction products, as well as in the manufacture of composites with “spray-up, hand lay-up, resin transfer molding and syntactic foam applications.”
