Details

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 for electric fire barrels, electric baking stoves, electric heaters, and heating. 

Advantage of Quartz Tube:

1. High purity , SiO2> 99.99%.

2. Working Temperature: 1250℃; Soften Temperature: 1730℃ .

3. Good thermal stability.

4. Acid-proof, Alkali-proof.

5. Excellent electrical insulator.

6.Transmission: Visible light >93%, UV light>85%.
