2. Dehydroxylated quartz tube
1. Application field
It is used in general lighting and industries where the hydroxyl requirement is not so high.
2.Product features
The quartz glass tube is melted and drawn by high purity quartz sand with one - step method. The transmittance at 200nm is from 20% to70%. The continuous fusion method can produce quartz glass tubes with the diameter 2mm to 450mm and the wall thickness from 0.5mm to 10mm, which can be cut with different length. We could resize the tube into different size from OD150mm to OD600mm with the customer's demand.
