Protecting your phone’s screen is essential in today’s digital age. A cracked screen not only impairs functionality but also diminishes the overall aesthetic of your device. Among various screen protectors, tempered glass stands out as a preferred choice, particularly due to its exceptional edge protection. This article explains why tempered glass offers superior edge protection compared to other screen protector options by examining the science behind it and its practical benefits.
Superior Strength and Durability
The main reason tempered glass excels in edge protection lies in its unique manufacturing process. Unlike regular glass, tempered glass undergoes thermal tempering or chemical strengthening. This involves heating the glass to extremely high temperatures and then rapidly cooling it. The rapid cooling process creates compressive stress on the surface while the interior experiences tensile stress. This combination of internal stresses makes tempered glass much stronger and more impact-resistant than standard glass or plastic films.
As a result, tempered glass provides better edge protection. When a phone is dropped, the edges are typically the first points of contact. Tempered glass is far less likely to chip or crack along the edges compared to plastic films or standard glass protectors, thanks to the compressive stress that helps absorb and resist impact forces.
