FRILITE® microspheres are non-combustible and mechanically stable for temperatures up to 1600°C.
FRILITE® microspheres are inorganic, insoluble and considered non-hazardous according to CLP.
FRILITE® microspheres produce minimal dust, have a low density and thus a high packing density.
FRILITE® microspheres are abrasion-resistant and mechanically stable during processing and use.
Hollow Mineral Microspheres
Hollow mineral microspheres are mono- or multicellular spherical and hollow particles in size typically below 500µm and with a specific gravity of below 1g/cm³ – which means that they are lighter than water. Depending on their chemical composition, density, colour and size they are widely used in various applications in order to lower the weight, influence the behaviour under high temperatures, allow smoother manufacturing and so on.
Cenospheres are lightweight, inert, hollow spheres. They consist largely of silica and alumina and are filled with gas. They typically occur as a by-product of coal combustion at thermal power plants and are carefully collected after being separated from the common fly ash.
