Hollow glass microspheres, made of Soda Lime Borosilicate Glass, are hollow spheres which grain size is 10-250microns, wall-thickness 1-2 microns, filled with inert air or gas. They are produced
at the high temperature of 700-800 degrees Celsius through complicated chemical and physical transformation. Hollow glass microspheres are white and the specific gravity of them is about
0.25-0.60g/cc. They have much merit, such as lightweight, great buoyancy, hard, rigid, waterproof, innoxious, insulative, low heat conductivity, higher mechanical strength and excellent chemical
stability,etc. Their surface was treated by the special way and the products are dispersed very easily in organic materials such as resin.
