Lightweight Hollow Glass Microspheres for Paint Additives

Glass bubble, 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.
glass bubble are produced at the high temperature of 700-800 degrees Celsius through complicated chemical and physical transformation. glass bubbles are white and the specific gravity of them is about 0.25-0.60g/cc.
Hollow glass microshpere have much merit, such as lightweight, great buoyancy, hard, rigid, waterproof, innoxious, insulative, low heat conductivity, higher mechanical strength and excellent chemical stability,etc. glass bubble surface was treated by the special way and the products are dispersed very easily in organic materials such as resin.

glass bubble are widely used in composite materials such as FRP, man made marble and man made agate. glass bubble can decrease the weight of the composite materials and the composite materials have excellent performance of sound insulation and heat preservation, and they can improve the mechanical performance of the composite materials such as strengthened rigidity, enhanced anti-impact property, excellent anti-breaking property and re-processing function.
