What is Hollow glass?

Hollow glass microsphere technology was developed in the 1950s as an outgrowth of the manufacture of solid glass beads. Hollow Glass Microspheres (HGMS) are near-perfect engineered spherical bubbles of thin-walled glass, approximately 50 microns in size, with a low density of between 0.1-0.4 g/cc. The glass type is amorphous and can come with low-purity or high-purity grades. Hollow glass microspheres are used to achieve high levels of Total Solar Reflectance (TSR) in coatings. These hollow particles can be used as lightweight fillers in syntactic foam or as hydrogen gas storage in the pharmaceutical industry. Initially used primarily as a filler for plastics in the 1960s, glass microspheres found applications in many industries and thousands of applications, including aerospace and military materials, molded plastic components, retroreflective highway signs, oil and gas, recreation, paints and coatings, and transportation.


What are the applications of hollow glass microspheres?

Hollow spheres also have uses ranging from storage and slow release of pharmaceuticals and radioactive tracers to research in controlled storage and release of hydrogen. Microspheres are also used in composites to fill polymer resins for specific characteristics such as weight, standability, and sealing surfaces. Microsphere techniques can assess blood flow in several tissues and organs (Rudolph & Heymann, 1967) and have been extensively used to assess RBF (Ackermann et al., 1980; Katz et al., 1971). Microspheres reduce the first-pass metabolism. Microspheres can be easily injected into the body because of their small and spherical size. Microspheres enhance the biological half-life and also improve bioavailability. Abstract. Hollow microspheres (micro balloons), loaded with drugs in their outer polymer shells, were prepared by a novel emulsion-solvent diffusion method.


How are hollow glasses made?

outh Blown Process shapes molten glass. Molten glass (Gob) is removed from the furnace with the help of cast iron rods and blown; more glass is gathered and blown/pressed in the desired mold made of wood or metal. This glassware is sent to anneal or remove strains in the chamber. Hollow glass microspheres (HGM) consist of outer stiff glass spheres with gas inside and exhibit some desirable properties such as lightness, low thermal conductivity, and low dielectric constant. On average, HGM has a diameter of 15 to 65 mm, a very thin wall of 0.5 to 1.5 mm, and a density between 0.12 and 0.60 g.


Price of Hollow glass

Hollow glass particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Hollow glass. A large amount of large amount will be lower. The Price of Hollow glass is on our company's official website.
