Glass Beads are an environmentally-friendly new type of inorganic lightweight insulation material, compared with organic heat preservation material, it is non-combustible, with higher strength and longer service life. This product is shaped in irregular spherical particles.The internal structure of every particle is porous cavity, and the surface is vitrify closed, so that it is smooth and gloss, and with very stable physical and chemical properties. It is light-weight, adiabatic, fire-resistant, high temperature resistant, aging resistant, and with low water absorption ration. These excellent properties make it adaptable for a lot of areas, such as Industry, agriculture, building materials, chemical industry, metallurgy, light industry etc.
