Hollow Glass Microspheres
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 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/cm 3; particle size is
2-130m; Due to its excellent advantages of light weight, bulk
density, lower thermal conductivity, higher compressive strength,
improved dispersion and liquidity.
The unique spherical shape of hollow glass microspheres offers a
number of important benefits, including: higher filler loading,
lower viscosity/improved flow and reduced shrinkage and warpage. It
also helps the hollow glass microspheres blend readily into
compounds and makes them adaptable to a variety of production
processes including spraying, casting and molding.
The chemically stable soda-lime-borosilicate glass composition of
hollow glass microspheres provides excellent water resistance to
create more stable emulsions. They are also non-combustible and
nonporous, so they do not absorb resin. And, their low alkalinity
gives hollow glass microspheres compatibility with most resins,
stable viscosity and long shelf life.
