Silica Glass Tube Feature




In addition to hydrofluoric acid, quartz glass has no chemical reaction withother acid. Its acid resistance is 30 times that of Ceramic.150 times that of stainless steel Especially the chemical stability at low temperature.
Which can not be compared with any other engineering materials.



The thermal contraction coefficient of quartz glass.
Can suffer severe temperature changes.
The quartz glass heated to 1100℃
also will not burst into cold water.



Quartz glass has good transmittance in all spectral bands from purple to red.
The visible light transmittance is above 93% specially in the ultraviolet spectral region.
And the maximum transmittance is over 80%.




The resistance of quartz glass is 10,000 times that of ordinary and has good electrical performance even at low temperature
