Anole Tight Dimention Tolerance Cutting Round Schott B270 3' Glass

We are engaged in manufacturing and exporting excellent quality Anole Tight Dimention Tolerance Cutting Round Schott B270 3'' Glass in Changsha, Hunan, China.
High borosilicate glass (also known as hard glass), is processed by advanced technology, using the conductive characteristic in high temperature to internal heat glass to melt it. The thermal expansion coefficient is (3.3+ /-0.1)x10-6/K, so some people also call it "borosilicate glass 3.3". It is a kind of special glass material that is of low inflation, high temperature resistant, high strength, high hardness, high transmittance and high chemical stability. For the excellent performance, it is widely used in solar power, chemical industry, pharmaceutical packaging, electric light source, craft decorations and other industries.
The thermal expansion ratio of high borosilicate glass is just about 1/3 of the common glass, which will reduce the influence of temperature gradient stress, and make its fracture resistance properties stronger. High borosilicate glass is the indispensable material in telescope and reflector due to its small shape deviation. It is also can be used to dispose high radioactive waste.

Basic property
-Very high transmittance of UV & IR and extremely low fluorescence intensity
-Extremely low thermal expansion ratio, strong thermal shock resistance and 450 for long term working temperature
-Excellent chemical stability, high resistance to water, acid, alkali and other organics
