Description
Milky white spiral quartz tube
By the distinctive technique our opaqu quartz glass tube is of high quality, good visual aspacts and stable physical&chemical properties. It serves as heating material for lamps, microwave oven, electrical baking oven, sterilcation containerand other consumer and industrial infrared application.
Further processing of trim cutting, fir polishing, bending and pinching can be done according to the requirements of custermer.
