High Light transmission quartz tube high temperature resistant quartz tube
High Light Transmission Quartz Tube is a special industrial technical glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. It is used in electric fire barrels, electric roasting stoves, electric heaters to generate heat. Quartz tubes can be roughly divided into the following types: transparent quartz tubes (outer diameter 1.5mm~300mm), ultraviolet filtering quartz tubes, colored quartz tubes, etc. The transparent fused quartz tube is a high-purity (more than 99.99%) quartz glass suitable for temperatures up to 1300 C. Thermal shock resistance is another important characteristic of quartz tubes.
