Tempered Glass (Temperedglass/reinforcedglass) belongs to the safety glasses. Glass has a very good wear resistance, and very hard, its Vickers hardness of 622 to 701. Tempered glass is actually a kind of prestressed glasses, in order to improve the strength of glass, usually using chemical or physical methods, on the glass surface to form compressive stress, glass under the external force of the first offset surface stress, thereby improving the load-bearing capacity, enhance the glass itself against wind pressure, the thermal, impact, etc. And the toughened glass protection film is for the mobile phone screen high security level protection.
