High-performance hollow glass microsphere is a kind of micron ultra-lightweight inorganic non-metallic glass material with hollow structure. It is filled with thin nitrogen and composed of soda-lime borosilicate glass. There are several types. The true density is 0.20-0.60g/cm³ with 2-130|jm in diameter, the compressive strength is 500-12000psi, the thermal conductivity is 0.05-0.11w/m.k. It is featured by light weight, high compressive strength, insulation, corrosion protection, fire prevention,smoothly mobility etc. It is a versatile and high-performance new lightweight filler.
