Quartz glass tube is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties,widely use in optical, chemical, semiconductor industrial, liquid crystal ,lighting, .ect. Heat resistance, light transmission, electrical insulation and chemical stability are very good.
Advantage of Quartz Tube:
1. High purity , SiO2> 99.99%.
2. High temperature resistant.
3. Good thermal stability.
4. Acid-proof, Alkali-proof.
5. Excellent electrical insulator.
6.Good light transmittance.
