The global hollow glass microspheres market is expected to grow from USD 4.2 billion in 2020 and to reach USD 8.5 billion by 2028, growing at a CAGR of 9.3% during the forecast period 2021-2028.
Hollow glass microspheres, also known as microbubbles, glass bubbles, or bubbles, are composed mostly of a borosilicate-soda lime glass combination formulation and have advantages such as strong heat and chemical resistance, as well as low density. These microspheres can also have conductive coatings applied on them. The adjusted thickness of the conductive coating on microbubbles provides superior shielding and conductivity qualities. Electronics, medical devices, military applications, biotechnology, and a variety of other specialist sectors can all benefit from these. The hollow glass microspheres have a remarkable spherical form that provides numerous significant benefits, including decreased shrinkage and warpage, better flow/lower viscosity, and greater fill loading. It also enables the hollow glass microspheres to easily mix into compounds, making them very flexible to a variety of manufacturing processes like as casting, spraying, and moulding.
Hollow glass microspheres are a well-known light weighting technique for injection moulded plastics used in transportation applications, and the transportation industry is projected to drive market revenues. These hollow glass microspheres assist to reduce part weight, improving fuel efficiency in automobiles, commercial vehicles, recreational vehicles, and aeroplanes while maintaining the essential physical characteristics. Microspheres have numerous benefits over other particle geometries for usage in biomedical applications, which is anticipated to fuel industrial growth from the healthcare sector. Construction, defence, mining, cementing, and drilling fluids are among the numerous applications.
