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
protectedagainstscratchand cracks, which reduce
the sensitivity of the screen to touch or disable the screen
altogether. A premium tempered screen protector offers

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
thesurfacetoughened. 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, itshattersinto verypieces,
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
thatmakesis 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 evenwhen heated. Plastics will begin to peel off
