BOROSOLICATE GLASS

High boron silicon glass (also known as rigid glass), the coefficient of linear thermal expansion (3.3 to 0.1) x10-6/K, it was also called "borosilicate glass 3.3". It is a low inflation rate, high temperature, high strength, high hardness, high light transmission and high chemical stability of special glass materials, because of their excellent properties, are widely used in solar energy, chemical industry, medicine packaging, electric light, crafts jewelry industry. It's good performance has been widely recognized by all sectors of the world, especially solar energy applications broader, Germany, the United States and other developed countries have been more intensive promotion.
