Product Features:

4.3 inch touch screen adopts 6H hardness chemically tempered glass.

What’s the advantage of chemically tempered glass?

Chemically tempered glass is suitable for use in the following construction occasions: where there is a requirement to reduce its own weight, and at the same time, there are certain requirements for impact strength, bending strength, and resistance to cold and heat shocks, such as windows and ceilings of agricultural greenhouses, doors, and windows of mobile houses, etc.

The advantage of chemically tempered glass is that it has not been transformed into a high-temperature process above the humidity, so there will be no warpage like physical tempered glass. The surface flatness is the same as that of the original glass. At the same time, the strength and temperature resistance is improved to a certain extent. It can be cut appropriately.

There are two main advantages of chemically toughened glass. The first is that the strength is several times higher than that of 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. The strength is improved at the same time. Improved safety. Safety in use is the second major advantage of tempered glass. The increased load-bearing capacity improves the fragile nature. Even if the tempered glass is damaged, it will appear as small fragments without sharp angles, which greatly reduces the damage to the human body. When the glass is damaged by an external force, the fragments will become small obtuse-angled particles similar to honeycombs, which are not easy to cause harm to the human body.

The resistance to rapid cooling and heating of chemically toughened glass is 2 to 3 times higher than that of ordinary glass. Generally, it can withstand temperature changes of more than 150LC, which has a significant effect on preventing thermal cracking.
