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

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.
