High borosilicate glass
High borosilicate glass
High borosilicate glass (also known as hard glass) is made by using the conductive property of glass at high temperature and by heating the glass inside to realize glass melting, which is manufactured by advanced production technology. The linear thermal expansion coefficient is 3.3 0.1) 10-6 / K, also known as "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Because of its excellent properties, it is widely used in solar, chemical, pharmaceutical packaging and electric light source. Craft ornaments and other industries. Its good performance has been widely recognized in the world, especially in the field of solar energy is more widely used, Germany, the United States and other developed countries have been widely promoted.
