Products Description
BAO RAN High purity quartz glass tube key features:
1
High temperature resistance glass can work under 1200°C continuously, and in short time can even work under 1450°C, its softening point is 1650°C, and the melting point is 1650-1800°C.
2
Corrosion resistant, Except hydrofluoric acid, quartz tube do not react with any acid and base except hydrofluoric acid. The stability is 30 times of the ceramic, and 150 times of stainless steel.
3
Excellent thermal shock stability.
4
High transmission to 85%.
5
Electric insulation, it is 10000 times of usual glass.

Why Choose Us
Introduction to Baoran Quartz Products
Donghai County Baoran Quartz Products Co., Ltd. was established in 2018. It is located in Tuofeng Industrial Zone, Donghai County, Lianyungang City, Jiangsu Province. The company mainly produces and sells quartz glass products. Its sales market covers more than 30 regions in China as well as multiple regions overseas, including Europe, America, Southeast Asia, and the Middle East.
Currently, the company has a production area of over 14,270 square meters. It has a quartz primary raw material production line, a quartz melting production line, and a semi-automated quartz glass processing line. The company produces an average of 300 tons of quartz tubes and 500 tons of quartz powder per year. It also produces 30,000 quartz components.
Our company mainly focuses on customizing quartz glass processing products. We serve multiple fields such as semiconductors, photovoltaics, aerospace, electronics, and electric light sources. Among them, electrically fused quartz glass is one of the few quartz producers in China at present.
Our Advantages
The heat-resistant quartz glass material produced by our company can withstand high temperature up to 1600°C. The high purity quartz glass tube used in ultraviolet disinfectant lamp has much better light transmissibility than ordinary quartz tube. And its life is 3-5 times longer than that of ordinary quartz tubes.
