Sil-Cell is an ultra-light, naturally occurring, Aluminum Silicate, microcellular filler that is inert, inorganic, non-toxic and pH neutral. Particles are formed by creating a structure of multicellular spherical bubbles.
Sil-Cell is exclusive to Silbrico and manufactured at our facilities in Illinois and Pennsylvania, as well as in Australia.
Sil-Cell is an excellent functional filler because of its inert properties, low density and structure. The multicellular structure provides greater tensile strength versus other types of micro fillers.
Due to its low effective specific gravity (E.S.G.), it is an exceptional density reducing agent for composites. Sil-Cell’s E.S.G. ranges from 0.17 to 0.336 g/cm3 compared to calcium carbonate type fillers that range from 2.5 to 2.8 g/cm3.

All analyses are shown in elemental form even though the actual forms present are mixed glassy silicates. Free Silica may be present in small amounts, characteristic of the particular ore body.
