- At roughly the same thickness as a sheet of copy paper, Corning® Willow® Glass is thin enough to be flexible while retaining its superior glass attributes. Willow® Glass provides the inherent benefits of glass in a mechanically bendable form-factor, enabling cost-efficient device processing.
- Willow® Glass can be used in displays to make thinner and lighter portable devices such as smartphones and tablets, without sacrificing device performance or reliability. It is also an ideal material for laminate applications like kitchen backsplashes and other vertical surfaces.
- Corning’s patented edge tabs enable practical use of Willow® Glass in roll-to-roll processing.
