What is Tempered Glass?

June 05, 2015

It is also called as toughened glass that is developed after regulated chemical or heat treatments that helps to increase strength of glass. The process of tempering adds inner glass surface into tension whereas compression works over outer surface. With this type of stress, whenever glass is broken due to any reason it does not splinter in form of jagged shards rather it collapse into granular chunks which do not cause injury. A tempered glass screen protector is made up of many layers where bottom layer is formed with absorbent silicon, then PET film and above this is an adhesive tempered glass with optical clear form which is finally secured with an oleophobic coating. With this typical arrangement it becomes at least five times stronger as compared to normal glass.
