Expanded perlite (expanded perlite production)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product "expanded perlite" represents perlite expanded by shock heating at a temperature of 870 - 1090 °C. The volume increase is 15 - 30 fold. Density of the expanded perlite is 60 - 300kg/m3. The most important uses of expanded perlite (normally treated to render it hydrophobic) include filled plaster board and wall elements insulating silicate-bonded boards for heat and flame protection insulating bitumen-bonded boards for back facing insulating boards and coating materials with poly-mer binders mortar (bonded with cement plaster or silicate) polymer dispersion mortars and plasters for thermal insulation and prevention of condensation on walls and ceilings (e.g. in swimming pools high humidity rooms). The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
