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 **0 for long term working temperature -excellent chemical stability, high resistance to water, acid, alkali and other organics -excellent scratch resistance, extremely high hardness and *0% lower density than common soda-lime glass -excellent electrical insulator for its very low alkali technical index Thickness: 0.7, 1.1, 1.*5, 2.0, 2.*5, 2.*5, 3.3, 3.8....*5.4(+/*0.2mm) Size: ***0×**0, ***0×***0, ***0×***0, ***0×***0(special size can be made customized) Density: 2.*3g/cm3 Refractive index: 1.****4 Transmittance: *1% knoop hardness: **0 Applications: -solar power -chemical industry -pharmaceutical packaging -electric light source -craft decorations
