Boron silicate glass is a globally recognized high quality, multi function float glass. Its physical, chemical and optical properties, such as high heat resistance, chemical resistance, high transparency and good surface quality, so that it can be applied to a variety of new and high tech glass applications. In addition to services outside the traditional application, more and more is used in the model and technology of special type glass application, such as electrophoresis technology, the application of micro fluid science and photovoltaic technology, fireplace, microwave oven, chemical pipes, resistance to high temperature mirror, high pressure resistant mirror resistance, acid-base mirror etc..
