Privacy Anti-Peep Tempered Glass For IPhone 12 Pro.

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
