Gorilla Glass is an alkali - aluminosilicate thin sheet glass which is well suited to survive common glass failures. Its unique composition allows a deeper layer of chemical strengthening thereby making it more durable and scratch resistant.Gorilla glass is strengthened through a High Ion Exchange (HIE) process which creates a deep compression layer on the surface of the glass. Tough yet sleek Gorilla Glass is an ideal cover glass for even the most innovative, thinnest, lightest electronic devices on the market. Available thickness from Yutai Optics:1.1,0.8,0.7,0.55mm. Even at its thinnest 0.55mm, it is tough enough to withstand the surface pressures typically experienced by touch devices.Yutai offers tempered process for Gorilla Glass, a tempered Gorilla Glass will be strong enough.
