Tempered glass is a type of glass that increases the strength of ordinary glass through physical and chemical treatment.The tensile strength of the glass is also increased.Therefore, toughened glass has strong mechanical strength and heat resistant impact strength.Therefore, the tempered glass can be divided into fully tempered and semi-tempered glass according to different treatment levels.

Features:
1. 5 times harder than the ordinary glass, the heat breakage strength is stronger than annealed and heat strengthened glass. 2.Once the breakage occurs, the glass will disintegrates into small cubic fragment,which is relatively harmless to the human . 3.It can withstand the temperature changed abruptly. 4. The glass can not be cut down once the glass have been tempered.
5.Toughened glass can guarantee the security of guardrail and increase the aesthetics.
The applications:
1.It will be a good choice to use for building curtain wal,the tempered glass is strengh,it is not to be break easily.And we can coat before toughening,so we can get Low-E tempered glass.
3.Interlay paper,cork mat, mold powder,and EPE between two sheets of glass
Production Process
Tempered glass is made by cutting the ordinary annealed glass into the required size, then heating it to about 700 degrees near the softening point, followed by rapid and uniform cooling (usually 5-6mm glass is heated at a temperature of 700 degrees for about 240 seconds and cooled for about 150 seconds). 8-10mm glass is heated at a temperature of 700 degrees for about 500 seconds and cooled for about 300 seconds. In a word, according to the thickness of the glass, the heating and cooling time are also different. After the toughening treatment, the glass surface formed uniform compressive stress, while the inside formed tensile stress, which improved the bending and impact strength of the glass, and its strength was more than four times of that of ordinary annealed glass. Tempered glass, which has been tempered, cannot be cut, ground or damaged in any way, otherwise it will be "shattered" due to damage to the balance of uniform pressure stress.
