Hollow glass microsphere / hollow glass beads / glass bubbles
Technical data sheet
Hollow glass microsphere, made of Soda Lime Borosilicate Glass, is
hollow sphere 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 microsphere is white and the specific gravity of them
is about 0.15-0.60g/CC. It has much merit, such as lightweight,
great buoyancy, hard, rigid, waterproof, innoxious, insulative, low
heat conductivity, higher mechanical strength and excellent
chemical stability, etc. It's surface was treated by the special
way and the products are dispersed very easily in organic materials
such as resin.
Hollow glass microsphere are widely used in composite materials
such as FRP, man made marble and man made agate. It can decrease
the weight of the composite materials and the composite materials
have excellent performance of sound insulation and heat
preservation, and it can improve the mechanical performance of the
composite materials such as strengthened rigidity, enhanced
anti-impact property, excellent anti-breaking property and
Hollow glass microsphere are applied in a wide range of fields such
as aviation, space flight, new bullet train, luxurious yacht,
adiabatic dope, bowing balls, in which they play a distinctive
Hollow glass microsphere is the excellent sensitized of emulsion
explosive. It can improve the detonation property of emulsion
explosive and prolong the shelf period of emulsion explosive.
When used in the resin putty, hollow glass microsphere can increase
the volume of resin putty, improve its polishing function.
