Closed-pore Perlite for fireprooding material

タイトルまたは説明

Closed-pore Perlite(Obturator),its requires special size perlite selected to be expanded after heating, and throgh precise control of temperature and material stayed in air time, so that  special perlite surface melting, stomatal closure, while the interior is honeycomb-like structure, being micro-spherical appearance.Compared with traditional porous perlite, besides thermal- insulation and acoustic insulation properties, its more benefit is high intensity, low water absorbability and good miscibility.

Main advantage
This product has high intensity, low water absorption  and easy separation etc.

Applications
Can improve mortar's mobility, widely used in insulation mortar of internal and external wall;
Used as decorative board and insulation board's light aggregate;
Can replace part of the floating beads;
Used in construction, metallurgy, industrial furnace (light firebrick aspects) and other industries
