We also have the following types of glass: (If you need, please contact us for the price)
1.Ultra high temperature quartz glass
The ultra-high temperature limit is 1450 degrees, the temperature is 1100 degrees, the hardness is up to 7 grades, the expansion coefficient is low, and the acid and alkali resistance is 93%.
2.Ultra-transparent ultra-thick tempered mirror
The color is close to colorless, or it can be said to be white, the light transmittance is 92-93%, and the temperature and pressure resistance after tempering treatment, like ordinary tempering, the processing thickness can reach 50mm.
3.Ultra-white tempered mirror
Close to colorless and transparent, light transmittance is 91-92%. Ultra-white glass is also called low-iron high-transparent glass. It has all processability, physical, mechanical and optical properties of float glass. It is characterized by ultra-white tempering than ordinary tempered glass. The rate is low.
4.Customized high temperature resistant high borosilicate tempered glass
