BPA Free Clear Borosilicate Glass Water Bottle utilizes the characteristics of conductive glass at high temperature, adopts advanced production technology, and realizes glass melting through internal heating of the glass. Since the coefficient of linear thermal expansion is (3.3±0.1)*10-6/K, it is also called "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high height, high hardness, high light transmittance and good chemical stability. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries.

BPA Free Clear Borosilicate Glass Water Bottle has a very low coefficient of thermal expansion, only about one-third of that of ordinary glass. This will reduce the effect of temperature gradient stress, resulting in greater resistance to fracture. Due to its very small deviation in shape, it can become the basic material for telescopes, mirrors and high-level radioactive nuclear waste disposal. High borosilicate glass will not break easily even when the temperature changes suddenly.
