Borosilicate float glass for optical instrument with best quality

Heat resistant Glass High transmission Light Stable chemical property High Acid Resistant Glass

Application: Fire resistant glass for doors and windows Fire-resistive partition Sealed insulating glass Used in curtain wall Fire resistant glass for ceiling, floor, sunshade, etc. Product characteristic: Excellent visual effect Powerful effect on fire resistance High resistance to thermal shock Without homogenization treatment, non spontaneous detonation Regulations: 1. Borosilicate single piece fire-resistant glass cannot be used in those areas which are explicitly demanded to have the function of heat resistance or radiation resistance. 2. Borosilicate single piece fire-resistant glass is processed by specific technology. It cannot be cut, drilled, polished, after it forming by special process. We will provide the detailed Toughened Parameters to our customers, if you need doing some other process on the glass by yourselves. Besides, please tell us your accurate size and shape requirements about the glass before ordering. 3. Avoid to be scratched on the surface of the glass during transit and installation.
