High borosilicate glass (borosilicate glass 3.3) is a special type of glass with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance, and high chemical stability (acid and alkali resistance, corrosion resistance).
Due to its excellent performance, it is widely used in industries such as solar energy, chemical engineering, pharmaceutical packaging, electric light sources, and craft accessories.
High borosilicate glass (borosilicate glass 3.3) has a very low coefficient of thermal expansion, which is about one-third of that of ordinary glass. This will reduce the impact caused by temperature gradient stress, resulting in stronger fracture resistance.
Due to its very small shape deviation, it will become an essential material for telescopes, reflectors, and mirrors.
