High Transmittance Quartz Glass Sheet Made in China
High Transmittance Quartz Glass Sheet is made of fused quartz in special industrial technology glass, which is a very good base material.Quartz glass has a series of excellent physical and chemical properties.
The feature of the clear quartz glass is as follows: high purity, strong transmission, strict size control, low OH content and so on. The deep processing would be done according to client's requirements, like neat cutting, fire polish, bending, sealing, polished and so on. OH content can be controlled less than 20ppm15ppm10ppm5ppm2ppm.
