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.
