What is the material?

A: Of cause, it is Glass!

We all know the screen protector is made of glass, but what kind of glass it is and how it was made into a protector?

So, it leads us to the classification of two materials: Glass and AB Glue. Regularly, the thickness of the glass ranges from 0.2mm to 0.4mm, some can be as thin as 0.15mm after being processed. Normally, the thinner the better, but it is also more difficult and expensive to make a piece of thinner glass.

Based on material, the glass for screen protector can be divided into Soda-lime glass and Aluminosilicate glass. Both of them can meet the need of today’s screen protectors on the market, though the Aluminosilicate one would be harder. When we look at the glass from a side, the greenish one is the Soda-lime glass while the Aluminosilicate one turns out white. The well-known Corning Gorilla belongs to the Aluminosilicate glass. However, most of tempered glass screen protectors are not made of Corning Gorilla due to its fancy price. Instead, the manufacturers will use glass from other brands which may not be as good as the Corning Gorilla ones but not so pricy.
