Corning Gorilla® Glass 3 Touch Screen Glass with NDR
Categories: Ceramic; Glass; Optical

Material Notes: Gorilla® Glass 3 with Native Damage Resistance™ (NDR) is an alkali-aluminosilicate thin sheet glass that is better able to survive the real-world events that most commonly cause glass failure. With its core composition, this glass enables improved damage resistance and toughness by helping to prevent the deep chips and scratches that cause glass to break. This glass is widely used in smart phone, tablet, and laptop displays, other touchscreens, optical components, and other high strength glass applications.
