Product Description
High Borosilicate Glass (also known as Hard Glass） is characterized by the use of glass to conduct electricity at high temperatures. The glass is melted by heating inside and processed by advanced production procedures. As the linear thermal expansion coefficient is (3.3±0.1)x10-6/k, It is also called “Borosilicate Glass 3.3". It is a special glass material with Low expansion rate, high temperature resistance, high hardness, high light transmittance and high chemical stability. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packing, electric light source, craft jewelry and other industries. Its good performance has also been widely recognized by all walks of life around the world, especially in the field of solar energy. Developed countries such as Germany and the United States have already invested this material in a wide range of applications.
