Translucent Quartz Tube

Writer:World Quartz  Date:

                                        

Opaque quartz tube (translucent quartz tube, milky-white quartz tube) is made of high purity quartz sand. It was pulled out from high temperature melting furnace. The surface of this kind of tube is smooth and the color is pearl-white. With the adoption of distinctive technique, opaque quartz glass tube has typical characteristics of good visual aspects and stable physical & chemical properties (Saint-Gobain satin translucent quartz type).
Application
It serves as material of infrared heating for heaters, micro-wave oven, electrical baking oven, car paint baking, sterilization container and other consumptive and industrial infrared application.
