TEMPERED GLASS is obtained by cutting ordinary annealed glass into the required size, then heating it close to the softening point, and then rapidly and uniformly cooling it. After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which greatly improves the performance of the glass. The tensile degree is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter.

It is also this characteristic that the stress feature becomes an important sign to distinguish true and false TEMPERED GLASS, that is, TEMPERED GLASS can see colored stripes on the edge of the glass through the polarizer, and black and white can be seen on the surface of the glass. Alternating spots. Polarizers can be found in camera lenses or glasses. Pay attention to the adjustment of the light source when observing, so that it is easier to observe.
After TEMPERED GLASS is broken, the fragments will be broken into uniform small particles and there is no general glass knife-like sharp corner, so it is called safety glass and is widely used in automobiles, interior decoration, and windows that open to the outside on high floors.
