1.Fatory supply price High purity Customized JSG2 Heat Resistance Round Frosted Quartz Glass Flange.
2.High purity of quartz glass flange :SiO2> 99.99%.
Quartz glass flange are melted and cut and ground from quartz sand, and their silica content can reach more than 99.99%. The hardness is Mohs grade 7, with high temperature resistance, low thermal expansion coefficient, acid and alkali resistance and good electrical insulation performance. Transparent quartz chip, visible light transmittance above 85%. There are milky quartz pieces, grinding stone quartz pieces can be processed quartz pieces.
Quartz has the characteristics of high temperature resistance, corrosion resistance, good light transmittance, moisture-proof and explosion-proof. Quartz has unique optical properties and is a material that can penetrate ultraviolet light. It can pass through the far ULTRAVIOLET, visible and near infrared spectra, and customers can choose from the wavelength range of 185 to 3500 nanometers.
Advantages of quartz glass flange:
8. Visible light transmittance >80%
