Hollow Glass Microsphere

Description

Product name: Pure White Hollow Glass Microsphere

   HOLLOW GLASS MICROSPHERES is a kind of ultra-lightweight inorganic non-metallic material with hollow structure, and it is a versatile and high-performance new lightweight material developed in recent years.

Appearance: White fine powder

Particle shape: Hollow sphere

Composition: Borosilicate

True density: 0.***0.2 g/cc

Average particle size: *****0 μ

Compressive strength: 4-6 MPa

Thermal conductivity: *0w/m.k

Advantages: substantial weight saving, low heat conductivity, high mechanical strength and fine chemical stability. With treated specially, they have the properties of lipophilicity and hydrophobicity and are very easily dispersed in organic materials such an resin.

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.

Its application of hollow glass in paint  It has the smallest surface area  and low oil absorption rate, can significantly reduce the consumption  of components in paint. The vitrified surface of it can realize the chemical corrosion resistant, and reflexaction on light. Therefore, the paint can prevent from fouling, corrosion, UV, yellowing and scratching etc. Thin glass inside it with compact arrangement, makes low thermal conductivity, so that paint coating has very good effect on heat insulation.

Paint that is extended with hollow glass microspheres has a lower viscosity than a paint filled to an equivalent volume with a nonspherical extender,  spherical particles have a low-energy surface that minimizes friction and drag. As a result, an equal volume substitution of these microspheres for irregularly shaped extenders will decrease the coating's viscosity. "Lower viscosity is a significant benefit in offsetting VOC levels in solventborne paint," says Shaker. " Adding microspheres to a high-VOC paint formulation allows formulators to remove some of the solvent and still maintain a viscosity that facilitates application and spreading properties."

Its application of hollow glass in Putty Compares with the tradition putty, the new type one adding with Hollow Glass Microspheres owns the advantages as follows: 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. Compared with the ordinary putty, new putty with 5% of it , can replace ****0% of talc, calcium carbonate, bentonite. Its volume can also be increased ****5% than that of ordinary putty, and saving resin about 8%.

Its application of hollow glass in the plastic It is used as filler of ultra-high molecular polyethylene. It is not only used as solid lubricant in process, but can modify the comprehensive mechanical properties of the ulta-high molecular polyethylene to improve its strength and abrasion resistance. Nylon with it has a higher tensile strength, impact strength, hardness and other improved menchanical properties and can prevent the material aging caused by the light and heat. With the increase of glass microspheres content, the Martin’s temperature of materials rises. It can used in the production of bearings, cameras, furniture and its accessories. It is added into rigid PVC to manufacture prefilled materials, pipes and plates. These materials have good in dimension, then their rigidity, heat resistance, productivity will be improved.

Its application of hollow glass microspheres in the Epoxy Tooling Board The Epoxy Tooling board filled with it 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 it. The oil absorption rate of it is much less than others like calcium carbonate, so the viscosity of materials was reduced.
