Core Performance Advantages of Quartz Glass Tubes
Quartz glass tubes are made from high-purity silica raw materials through high-temperature melting and precision processing. Their superior performance far exceeds ordinary soda-lime glass and borosilicate glass, adapting to extreme working environments that conventional materials cannot withstand.
1. Extreme High and Low Temperature Resistance
This is one of the most iconic properties of quartz glass tubes. With a melting point of up to 1730°C, they can work stably for a long time under continuous high temperatures of 1100°C. Meanwhile, they feature excellent thermal shock resistance—they will not crack or deform even with instant temperature changes from high heat to room temperature. In addition, they can withstand ultra-low temperature environments close to -200°C without brittle failure, making them suitable for both high-temperature heating processes and cryogenic experimental scenarios.
2. Outstanding Chemical Corrosion Resistance
Are you troubled by pipeline corrosion, aging, and short service life in chemical experiments and industrial production? Quartz glass tubes solve this pain point perfectly. They are inert to most acidic, alkaline, and organic chemical reagents. Unlike metal tubes that are prone to oxidation and corrosion or plastic tubes that are easily dissolved and deformed, high-purity quartz tubes hardly react with chemical media, ensuring the purity of experimental samples and industrial raw materials while extending equipment service life.
3. Excellent Optical Transmittance
Quartz glass boasts unparalleled light transmission performance, especially in the ultraviolet, visible, and infrared spectral bands. It achieves a light transmittance of over 90% for ultraviolet rays, which ordinary glass cannot match. This unique optical property makes it a key material for optoelectronic equipment that requires precise light transmission and spectral analysis. Moreover, it has low optical distortion and stable light transmission performance, not affected by temperature and environmental changes.
4. Stable Physical and Insulating Properties
Quartz glass tubes feature high hardness, low thermal expansion coefficient, and excellent dimensional stability, with minimal deformation under high temperature and high pressure. In terms of electrical performance, they have superior high-temperature insulation and low dielectric loss, effectively isolating current and resisting high-voltage breakdown. They can maintain stable insulation performance in high-temperature and humid environments, which is critical for electrical and electronic precision equipment.
