Detailed Product Description

Hollow glass microspheres are more economical,and adjusting density.

Product Introduction

High-performance hollow glass microsphere is a kind of ultra-lightweight inorganic non-metallic material (powder) with hollow structure(microsphere), and it is a versatile and high-performance new lightweight material developed in recent years. It will be the new composite (mainstream )materials at twenty-first century. Its true density is 0.20-0.60g/cm³ with 2-120μm in diameter. It owns features with light weight, large bulky, low thermal conductivity, high compressive strength, smoothly mobility etc.

Applications

Its applications are in the fields of Thermal insulation coating, putty, plastic casting polyester, FRP ,SMC, synthetic foam, adhesives, printed circuit board substrate, RTM, bowling, fan blades, & caulking materials, emulsion explosives, golf, sealant, pipeline insulation materials, artificial marble, PVC foam, low density oil drilling, light cement, and other deep-sea buoy etc.

Appearance: White fine powder

Particle shape: Hollow sphere

Composition: Soda lime borosilicate quality

True density: 0.15-0.25g/cc

Average particle size: about 40-60μ

Compressive strength: about 1.5-5MPa

Thermal conductivity: 0.03-0.06w/m.k

1.The man-made wood filled with hollow glass microspheres can provide excellent quality assurance for parts of furniture, ornaments and sculptures. In the original formula, the product density can be adjusted by adding different percentage of hollow glass microspheres.

2.The oil absorption rate of hollow glass microspheres is much less than that
of other common fillers like calcium carbonate, so the viscosity is
significantly lower also.

3.Compared with traditional mineral additives, hollow glass microspheres have a better mobility, which are suitable for the manufacture of large area, thin
wood board. The wood materials with addition of hollow glass microspheres are more easily nailed. It can avoid the phenomenon of cracking existing in the traditional formula of artificial wood in general after nailing.

Hollow glass microspheres mixture:

The filling content of hollow glass bead generally is between 5% -20%. It can
be easily mixed with resin, and is proposed to be added at the final stages of
mixing with a slower mixing speed.

If the high-pressure pump required, it should be determined that whether the
strength of hollow glass microspheres can meet the requirement in advance.

Note: The mixture method of hollow glass microspheres is also important, we
strongly recommend that the mixing speed of adding hollow glass microspheres
should be less than 100 r / min.

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 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.
