Tempered glass belongs to safety glass.Tempered glass is actually a kind of prestressed glass, in order to improve the strength of glass, usually using chemical or physical methods, forming compressive stress on the surface of glass, glass under external force first offset surface stress, thereby improving the bearing capacity, enhance the glass itself to resist wind pressure, cold and heat, impact, etc.

When the glass is damaged by external force, the debris will become a honeycomb like obtuse small particles, not easy to cause serious harm to the human body;The impact strength of tempered glass of the same thickness is 3-5 times that of ordinary glass, and the bending strength is 3-5 times that of ordinary glass.Has good thermal stability, can withstand the temperature difference is 3 times of ordinary glass, can withstand the temperature difference of 300℃.
