Descripción del producto

Vitrified Micro Bubbles (VMB) 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.
