Outstanding Properties of Quartz Glass Materials

*High purity quartz with silica content 99.99%
*very low thermal couductivity, excellent thermal vibration resistance
*Very high deformation temperature and softening temperature
* High dielectric electric field strength, low dielectric loss, and low conductivity
* Optical transmittance in an extremely wide spectral range from ultraviolet to infrared
* Very good chemical stability, does not react with water, salt solutions and most acids.
* Excellent radiation resistance.
Further-processing of transparent quartz tube:
Ends closing, sand blasting, polishing, bending, cutting, pinching, burning mouth and so on.
