Owning a touch screen phone or tablet requires care for the outside look of the device, especially the screen, which is the most valuable part of the device. Its wise to have the screen protected against scratch and cracks, which reduce the sensitivity of the screen to touch or disable the screen altogether. 

A premium tempered glass screen protector offers maximum screen protection to your phone or tablet device.

Tempered glass is made by subjecting to thermal treatment or by

treating it with hydrofluoric acid. This kind of treatment increases the compressive on the surface of the glass making the surface toughened. This makes tempered glass resistant to heat and pressure applied on the surface. Unlike normal glass which breaks and separates the pieces apart, when tempered glass breaks, it shatters into very pieces, which may still be intact or split depending on the surface coating.

 These screen covers can withstand a lot of heat that may emanate

from keeping the phone in a pocket that gets heated by the body, without undergoing thermal expansion. This is a property that makes it better than plastics and other forms of screen protectors, which easily undergo thermal expansion and damage. Because the glass does not heat up, the adhesive keeps to the surface even when heated. Plastics will begin to peel off
