EXTRALIT is a very fine-grained expanded perlite consisting of micronised powder extracted from filters after the expansion process of different perlite grain sizes. The use of originally selected raw materials and the thermal expansion process with methane burners result in an inorganic and stable product.
EXTRALIT, derived from quality raw materials, is light, inorganic, heat-insulating and non-combustible. As it is also stable and chemically inert, it is resistant to biological attack and does not deteriorate or rot, even after long periods of storage.
Uses:
- Industrial and manufacturing sector
- Lightening of artefacts
- Filler for rubbers, plastics, paints and sheaths
