If you want to know what material tempered glass film is, first understand what tempered glass is. Tempered glass is a reinforcing material used when traditional annealed glass is not strong enough. Tempered glass is made of heat-treated glass, which increases the strength of the glass by more than four times.

Tempered glass is made of oil and scratch resistant gorilla glass. When your fingers slide more smoothly on these screen protectors, it enhances your usability experience. They can prevent excessive fingerprints and oil stains. You may not even notice that they are located at the top of the mobile screen.

Tempered glass process flow:

White finished products - QC inspection - cleaning treatment - chemical tempering - insulation and cooling - cleaning and drying - packaging. Due to the slow exchange rate of potassium and sodium ions, the exchange time for glass to have a high stress value and a stress layer thickness that meets usage requirements varies from 1 hour to 8 hours.

Tempered glass is the most common screen protector film on the market, which can ensure that the display screen is 100% not damaged by external forces. It is formed by heating the glass and immediately cooling it to form a type of glass that is not as prone to breakage as all other glass. This type of screen protector film is multi-layer, with silicon chips embedded at the bottom, which can absorb impact and form bonded tempered glass. This screen protector can also resist collisions and scratches on the phone screen.
