D 263
DESCRIPTION
| D 263 is well suited for many applications because of its specific properties and large range of thicknesses. Its special fire-polished surface makes this thin glass able to be used without grinding and polishing. D 263 is a borosilicate glass which is produced by melting the purest raw materials, making it very resistant to chemical attack. This product features a large thickness range, excellent flatness, easy to cut properties, and high light transmission. |
