Glass bubble,Hollow glass microspheres , Glass sphere beads, Manufacturer & suppliers

Glass bubble, made of Soda Lime Borosilicate Glass, are hollow spheres which grain size is 10-250microns, wall-thickness 1-2 microns, filled with inert air or gas.
glass bubble are produced at the high temperature of 700-800 degrees Celsius through complicated chemical and physical transformation. glass bubbles are white and the specific gravity of them is about 0.25-0.60g/cc.
Hollow glass microshpere have much merit, such as lightweight, great buoyancy, hard, rigid, waterproof, innoxious, insulative, low heat conductivity, higher mechanical strength and excellent chemical stability,etc. glass bubble surface was treated by the special way and the products are dispersed very easily in organic materials such as resin.

glass bubble are widely used in composite materials such as FRP, man made marble and man made agate. glass bubble can decrease the weight of the composite materials and the composite materials have excellent performance of sound insulation and heat preservation, and they can improve the mechanical performance of the composite materials such as strengthened rigidity, enhanced anti-impact property, excellent anti-breaking property and re-processing function.

FROM:chnchemical

Microsphere is a term used for small spherical particles with diameters of the Order of the micrometer (typically 1 pm to 1000 pm (1mm)). The microspheres are sometimes called microparticles.

microspheres can be manufactured from various natural and synthetic materials. Glass microspheres, polymer microspheres and ceramic microspheres are commercially available. Solid and hollow microspheres vary greatly in density and, therefore, are used for different applications. The hollow microspheres are commonly used as additives to reduce the density dun material. Solid microspheres have numerous applications depending on what material they are constructed and what size they are.

Polyethylene and polystyrene microspheres

are two most common types of polymer microspheres.

Polystyrene microspheres

are commonly used in biomedical applications because of their ability to facilitate processes such as cell sorting and precipitation immunio. Proteins and ligands on polystyrene absorb easily and permanently, which makes polystyrene microspheres suitable for medical research and biological laboratory experiments.

Polyethylene

microspheres are commonly used as permanent or temporary care. Lower melting temperature polyethylene microspheres allows to create structures and porous ceramic materials dautres. High sphericity of polyethylene microspheres, as well as the availability of color and fluorescent microspheres, makes them highly desirable for the visualization and the analysis of the flow of fluid flow, microscopy techniques, health sciences, troubleshooting processes and applications Much research. Polyethylene loaded microspheres are also used in digital electronic paper displays.

Glass microspheres are mainly used as a filler and volumizer for weight reduction, road safety reflector, additives for cosmetics and adhesives, with limited applications in medical technology.

Ceramic microspheres are mainly used as the grinding medium.

microspheres vary considerably in quality, sphericity, luniformité size and particle size distribution. The microsphere must be selected for each application.

We believe that the microspheres are Mon least understood commercial products. Most people associate microspheres with their use as filler in plastics and composite materials (hollow glass microspheres). This nest quune many applications.

THE USE seconds less microspheres is included in cosmetics and personal care industrys. Ceramic microspheres and polyethylene are used in cosmetics to create a soft and silky texture, and to provide a filler for reducing wrinkles on the skin. The personal care industry use polyethylene microspheres exfoliating agents in shampoos and shower gels (colored objects in suspension).

Spheres of barium titanate glass with IR than 1.9

barium titanate glass microspheres are excellent to be used as a functional additive for reflective paints and coatings. Spheres with sizes of approx 50 microns (~ 0.002 inch) average diameter to provide a sufficiently small size for most of the coatings while providing a size large enough for a large amount of light reflectance. Glass spheres, barium titanate are offered partially coated aluminum retroreflective version uploading in transparent coatings, and uncoated spherical glass powder for use in colored paints.

glass beads barium titanate offers one of the most high refractive index with an IR greater than 1.9 which provides retroreflectivity high intensity of these areas.

For applications requiring a load to high density areas of barium titanate glass offer 4 glass bubble.5g/cc density, which is almost double that of glass spheres soda lime most common. More dune high density glass spheres barium titanate has a hardness of approx 55-65 on Gardner and ladder resistance lécrasement more than 30,000 psi (207 MPa), making these areas highly resistant in environments with high wear .

High density glass microspheres|4.5 Density Their size ranges from 30 microns to 1 mm

barium titanate glass microspheres are glass spheres high density solids. At a density of 4.5g/cc these solid glass spheres can be used for many scientific applications where high density and optical clarity is required. In addition to high density, they also offer a refractive index greater than 1.9.

Bulk quantities are available in 30-100um and vary in size from 0.3 to 1.0 mm.

For experiments requiring the highest accuracy pearls can be purchased with grades classified> 90% of spheres in a specific size range. Standard sizes include narrow ranges below.

38-45um, 53um 45, 53-63um, 75um, 63-90um glass bubble, 75-90, 106um, 0.25mm-0.3mm, 0.3mm-0, 35mm, 0.36mm 0.42mm-,-0.43mm 0.5mm, 0.5mm, 0.6mm, 0.6mm, 0.7mm, 0.71mm 0.85mm d, and 0.85 mm to 1.0 mm.
