In the construction industry, perlite is used for the production of dry building mixtures as a filler, building materials (slabs, blocks), and also has an independent significance as a bedrock sound insulator and insulation Expanded perlite is also called agroperlite - it is widely used in plant growing. Its especially important qualities include moisture and air consumption, neutral pH, low thermal conductivity and unlimited shelf life.
Expanded perlite is widely used in many industries, the scope of application is determined by the fraction (granule size), the most common are three:
• Fraction 0-0,16 mm - filtroperlit.
• Fraction 0,16-1,25 mm - building perlite.
• Fraction 1.25-5 mm - agroperlite.
