Size: 10-20mesh; 20-40mesh; 30-50mesh; 40-80mesh; 70-90mesh;

Production process is: made of selected perlite raw ore through crushing, preheating and high temperature expansion.

The general characteristics of expanded perlite: loose and porous interior, white appearance, uniform and loose particle size.

Physical characteristics: small capacity, low thermal conductivity

Chemical characteristics: good stability, non-flammable, non-toxic, tasteless, sound-absorbing, acid-alkali resistance and other characteristics.

Reinforced products: waterproof products that spray silicone or other waterproof materials on the surface of expanded perlite to form hydrophobic structure.
