Borosilicate Glass Rod

High borosilicate glass (also known as hard glass), because the coefficient of thermal expansion coefficient is (3.3 ~ 0.1) x 10-6/K, also known as borosilicate glass 3.3". It is a special glass material of low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability, because of its excellent properties, is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light, craft accessories industry. Its good performance has been widely recognized by all walks of life in the world, especially in the field of solar energy application is more extensive, Germany, the United States and other developed countries have been more widely promoted.
