Hollow glass Microspheres 中国空心玻璃微珠

The high-performance hollow glass microspheres, a kind of ultra-light inorganic non-metallic powder with hollow “ball-bearing” shapes, have been developed into a new type of high performance lightweight material and have been widely applied in recent years. It will be the main direction for new-type compound materials in the 21st century. Its true density is 0.20-0.60 g/cm3; particle size is 2-120μm; Due to its excellent advantages of light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, and excellent chemical stability, it can be mainly used as filler in painting, rubber, plastics, FRP, artificial stone, putty, exploitation of oil and gas and other materials.

高性能空心玻璃微珠是一种中空的圆球粉末状超轻质无机非金属材料，是近年发展起来的一种用途广泛，性能优异的新型轻质材料，它将成为二十一世纪新型复合材料的主流。其真密度在0.20-0.60 g/cm3，粒径在2-120μm之间，具有重量轻，体积大，导热系数低，抗压强度高，流动性好等特点。它主要运用于涂料，橡胶，塑料，玻璃钢，人造石，原子灰，油气田开采和其它材料的填充剂。

Sinosteel Maanshan Institute of Mining Research Co., Ltd., established in 1963 and directly subordinate to the former Ministry of Metallurgical Industry, is a large comprehensive research and development institution in China’s metallurgical mine field. It is one of the units that was approved early by the Academic Degree Awarding Committee of the State Council to have the autogenous right to award the master academic degree and one of the units first approved by the State Economic and Foreign Trade Ministry to have the right to import and export products. The institute was transformed into a
