Perlit
Perlit
Perlite is light and inert material. Perlitic products are made from amorphous volcanogenic aluminosilicate rock, having very specific properties. Mineral structure contains water, which is expanding under heat, transforming to steam and forms foaming structure.
Perlitic ore is used in building industry as filling material. Unusual combination of foaming structure and inertness permits to use expanded unpowdered perlite for cryogenic insulation, hydroponics, in light construction mix and texture coatings.
Due to combination of inert composition and uneven structure («crushed glass»), expanded powdered perlite is used in liquids filtration, very saturated with suspended particles, ensuring high efficiency of the process. Perlite filter aids have better potential to trap significant amount of suspended particles without filter blocking.
