It is made by selected specific particle size ore to be expanded by
heating in furnace. And the precise control of time temperature and
raw material stayed in air makes product surface melting,stomatal
closure,irregular spherical,internal structure to be porous
cavity,surface vitrified closed,glossy smooth.And it is new
insulation materials with very stable physical and chemical
properties.
Main features
Light weight、heat、sound insulation、fireproo、thermostability、aging
resistance、small water absorption rate,etc.
