Solid Glass Microspheres, also called glass beads, provide multiple benefits including enhanced processing, excellent chemical and heat resistance, thermal stability, low oil absorption, and are often used in automotive, electrical, household appliance, adhesives, packaging, paint and construction industries. Glass is non-toxic, extremely stable and recyclable. Cospheric specializes in solid glass microspheres with perfect sphericity, tight tolerances and particle size distributions for biomedical, life sciences, microscopy, automotive, high-tech equipment and specialty applications.

Borosilicate Glass is well-known for its durability, low coefficient of expansion, low density, high softening point, high resistance to acids and thermal shock, compared to other glass formulations. The chemical composition consists primarily of silicon oxide (SiO2) and boron oxide (B2O3). Coefficient of thermal expansion for borosilicate glass is about one third of other glass compositions making it resistant to thermal shock, which is critical for those applications where minute deviations in shape might matter. Due to the wide range of operating temperatures, borosilicate glass microspheres are highly desirable in chemical, pharmaceutical and research processes, specifically in laboratory environments, where processing at high temperatures takes place.
