What is tempered glass?

Tempered glass is a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external forces, it first counteracts the surface stress, thereby improving the bearing capacity and enhancing the resistance of Wind pressure, cold and heat, shock and so on.

Advantages of tempered glass

1st, the strength of tempered glass is increased several times compared to ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass, which not only improves strength but also improves safety.

2nd, tempered glass is safe to use. Even if the tempered glass is damaged, it has small fragments without acute angles, which greatly reduces the harm to the human body. Tempered glass have better resistance to temperature differences,which more than 150LC.So tempered glass has a significant effect on preventing thermal cracking.

Use of tempered glass in screen protector

Since 2012, tempered glass has been applied to the field of mobile phone protection, and toughened tempered glass screen protector was designed.It has the benefit of high hardness, low toughness and when the phone transmits tension, the tempered screen protector will withstand the tension. This greatly reduces the tension on the main screen.
