Product features: Made of 3.3 borosilicate glass, borosilicate glass with first level hydrolysis resistance, high chemical stability, good mechanical properties, durability, heat resistance, corrosion resistance, impact resistance, and other characteristics.

High borosilicate glass is made by utilizing the conductive properties of glass at high temperatures, melting the glass by heating it inside, and processing it through advanced production techniques. SiO2 (silicon oxide)>80.2 ± 0.3% and B2O3 (boron oxide)>12.7 ± 0.3% are present in the glass tube, indicating a high content of silicon and boron.

Suitable for manufacturing all glass solar vacuum tube collection tubes; We can customize glass crafts such as high borosilicate glass tubes, industrial tubes, process tubes, lighting tubes, etc. with various diameters, wall thicknesses, and specifications according to the different needs of customers. Suitable for manufacturing all glass solar vacuum tube heat collection tubes, producing energy-saving lamp cores, and various handicrafts.
