Toughened Glass is made from annealed glass that has been heated to about 650 ° C and then cooled rapidly. Due to the increased heat treatment and rapid cooling of the glass, particularly between the surface and the inside of the glass, the treatment produces different physical properties. This results in compressive stress on the surface and improved flexural strength of the glass.
Before dipping, the glass must be cut or squeezed. Indeed, once hardened, it can not be reworked.
Toughened Glass is widely used in many applications.
Toughened Glass is four to five times stronger than annealed glass of the same size and thickness against impact.
Toughened Glass has a higher thermal resistance and can withstand a high temperature differential of up to 250 ° C.
Toughened Glass is considered a safety glass. It is difficult to break and even in case of breakage, it disintegrates into relatively harmless little globules.
