Application of Hollow Glass Bubbles in Atomic Ash (Putty)

Compared with the ordinary putty, new putty with 5% of hollow glass microspheres, can replace 10 ~ 20% of talc, calcium carbonate, bentonite. Its volume can also be increased 15-- 25% than that of ordinary putty, resin is saved by 8%.

Application of Hollow Glass Microspheres in Putty

Appearance:      White fine powder

Particle shape:  Hollow sphere

Composition:     Soda lime borosilicate glass

True density:    0.20-0.60g/cc

Average particle size: about 2-120μm

Compressive strength:  about 4-69MPa

Thermal conductivity:  0.03-0.06w/m.k


Compared with the traditional atomic ash, the new type of one with hollow glass microspheres owns 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 10 ~ 20% of talc, calcium carbonate, bentonite. Its volume can also be increased 15-- 25% 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.
