Product Description

Product Description

Quartz Glass Tube and Quartz Glassware 

High-purity quartz glass tube is a special industrial glass material made of high-purity silica raw materials. Featuring ultra-low thermal expansion, excellent high-temperature resistance, superior chemical stability, perfect optical transmittance and reliable electrical insulation, it is one of the most essential core materials for high-end industrial, electronic, optical, medical and laboratory fields. Our factory supplies full-series quartz tubes with complete specifications, stable quality and customizable processing services.

Core Product Advantages

• Ultra-high Purity: Raw material SiO2 content reaches 99.99%–99.9999%, extremely low impurity content, ensuring stable performance in high-end precision equipment.

• Super High Temperature Resistance: Continuous working temperature up to 1200°C, short-term maximum temperature 1500°C, suitable for various high-temperature heating and reaction environments.

• Excellent Thermal Shock Resistance: Thermal expansion coefficient is only 1/12 of ordinary glass, capable of withstanding drastic temperature changes without cracking.

• Strong Chemical Corrosion Resistance: Resistant to strong acid, aqua regia and high-temperature gas erosion, far more stable than stainless steel and ceramic materials.

• Good Optical & Insulation Performance: Full-spectrum light transmission and excellent electrical insulation, widely used in optics and electronic industries.
