Application of Glass Microsphere

Due to its excellent advantages of light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, it finds application in

Use of Hollow Glass Microsphere in Rubber & Plastic Industry:

Injection molded components and extruded profiles; Sheet molding compounds (SMC) and bulk molding compounds (BMC); Automotive, aerospace and marine transportation; FRP; Artificial Stone; Furniture and molded decor; Electronics and appliances; Packaging films; Polymer/wood composites and siding

Hollow glass microspheres have multiple uses but are prominently used in the rubber industry for making products such as silicone rubber sealants. The major advantage of these hollow glass microspheres is they result in weight reduction. PETRA MicroLite glass microsphere provides adequate insulation, durability, and stability which is helpful in transportation as well as various other applications.

The hollow glass microspheres are also used in the plastic industry. A lot of studies after a thorough research have concluded that when plastic is used with hollow microsphere also known as hollow glass beads can make their outputs lighter, more durable, and stronger along with reducing the requirement of increased costings and materials used during the process.

Hollow microspheres have a very significant impact on the nature of products in terms of insulation, resistance, structure, durability, thermal conductivity and so on which changes the applications of the products drastically.

Use of Glass Microspheres in Construction Materials

Caulks and sealants; Cultured marble; Preformed concrete; Putties; Spackling; Spray-up/lay-up Mastics; Paints and coatings; Potting compounds Hollow glass sphere has wide uses in the thermal insulation of construction materials due to their high strength, low density, and chemical resistance. The energy-saving feature of a hollow microsphere is very integral to the construction industry as energy is being used significantly in residential sectors. PETRA MicroLite Glass Microspheres are excellent for thermal insulation applications. Studies have also proved that the use of glass microsphere results in increased thermal and mechanical characteristics of foams used for insulating.

Use of Hollow Glass Spheres Drilling Fluids in Emulsion Explosives for Mining And Oil & Gas Sector:

Emulsion explosives; Lightweight cement slurries; Low-density drilling fluids (hollow glass spheres drilling fluids) Buoyancy modules and risers Deepsea pipe and flowline insulation; Syntactic foam

In the face of rising expenses and reduced prices of commodities, the mining industry is facing hurdles in a bid to reduce costs and work on improving productivity at the same time. Hollow microspheres are used in the making of emulsion explosives, which is the result of a lot of research performed to understand how to enhance its performance as well as the ability and one of the most important features to adjust the density. The biggest advantage of these hollow glass microspheres is that they have proved to significantly reduce cost.

While in the oil and gas industry, the hollow glass beads are used by adding them to the drilling fluids to reduce their density. These hollow glass spheres drilling fluids can be utilised in drilling in various conditions which may be either balanced or underbalanced. Hollow glass spheres drilling fluids are used in oil extractions and drilling not only results in the conservation of energy but also reduces costs and can be re-used, thereby becoming user-friendly and more sustainable to an extent.

Use of Hollow Microsphere in Biomedical

Glass microsphere has now been included in biomedical due to its newly found purpose i.e targeted drug delivery. These hollow glass microspheres can help to control the dosage of medicines and also regulate its interval thus allowing better treatment of patients. This feature also allows for consistent drug release to maintain a certain level of plasma. The shape of the glass microsphere allows increased retention in the tract and thus increases therapeutic effects and longevity. It also allows targeted delivery in the stomach, controlled release to eliminate irritation caused by gastric secretions. Due to various advantages, these hollow microspheres are now being researched to develop more usage in healthcare.

Use of Hollow Glass Microsphere in Coating

In terms of coating, glass microspheres are considered a perfect fit as they have magnanimous mechanical as well as heat-insulation characteristics. The hollow glass sphere is used as raw material extensively in the coating industry as light reflectors due to easy availability, have a very low density, and are spherical in shape. Thus hollow glass microsphere is a boon in terms of raw materials for coating purposes that result in enhanced performance overall.

The chemically stable soda-lime-borosilicate glass composition of hollow glass sphere provides excellent water resistance to create more stable emulsion.

HOLLOW GLASS MICROSPHERE : GLASS BUBBLE SPHERE (HOLLOW GLASS BEADS)

Hollow Spheres are only a fraction of the density of commonly used resins. It only takes a small addition by weight of Hollow Glass Microspheres to displace heavier materials. Hollow glass sphere simultaneously add volume and reduce density. If you are looking for buoyancy, no filler performs as well as Potters Hollow Spheres. Additionally, they can save material costs; on a volume basis, microspheres are a fraction of the cost of resins.
