Warm reminder
Please contact us before placing an order. The product price is for reference only and does not represent the specific selling price. Because there are too many product sizes, parameters need to be provided for processing. Outer diameter, thickness, length and quantity of quartz tube. For the length, width, thickness and quantity of square pieces, it is best to provide the drawing mailbox so that we can make an accurate quotation

Brand: Teng jun
We are a manufacturer of fused quartz glass.
1) High purity: SiO2> 99.99%.
2) Operating temperature: 1250; Softening temperature: 1730.
3) Excellent visual and chemical properties: acid resistance, alkali resistance, good thermal stability
4) Health and environmental protection.
5) No bubbles, no air pipeline.
6) Excellent electrical insulation.

Features of quartz tube/quartz glass tube:
1.High purity: 99.99%-99.999% SiO2.
2.Strong Hardness: Moh's hardness 5.3-6.5.
3.High temperature resistance: can work under 1200°C continuously,
4. Acid and Alkali resistance:except
quartz glass does not react with any acid and base. Its stability is 30
times of the ceramic, and 150 times of stainless steel
4. Electric insulation: 10000 times of usual glass.
5. High light transmittance: 85%-95%, depends on different spectrum.
6.Excellent thermal shock stability: Small thermal expansion coefficient, 5.5×10-7/.
