Application of Hollow Glass Microspheres in Atomic Ash (Putty)

Product Description

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 *1st century. Its true density is 0.***0.*0 g/cm3; particle size is ****0μm; 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 used as filler in painting, rubber, plastics, glass steel, man-made stone, putty, exploitation of oil and gas and other materials.

The high-performance hollow glass microspheres are alternatives to conventional fillers and additives such as silicas, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties.

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.
Compared with the traditional atomic ash, the new type of one with hollow glass beads own the advantages as follows:

1. Easy preparation and production, the hollow glass microspheres can be well mixed by a simple low-speed mixer. Its product has a feature of light weight and large volume.

2. Compared with the ordinary putty, new putty with 5% of hollow glass
microspheres, can replace *0 ~ *0% of talc, calcium carbonate,bentonite. Its volume can also be increased ***- *5% than that of ordinary putty, resin is saved by 8%.

3. The oil absorption rate of hollow glass microspheres is much less than that of talc and other fillers. So it has a significantly lower viscosity.

4. Putty with hollow glass microspheres can be easily polished with advantages of time saving, labor-saving and dust reduction.
