CORNING Willow Glass
CORNING Willow Glass, developed by Corning Incorporated, is a revolutionary ultra-thin flexible glass with a thickness of just 0.1 mm (paper-like lightness). It combines the inherent advantages of glass—high optical clarity, high-temperature resistance, and surface hardness—with exceptional flexibility, enabling it to bend, curve, or conform to folded designs without sacrificing scratch resistance or durability. Ideal for flexible displays, wearable tech, curved lighting, and solar cells, it serves as a critical material for next-generation electronics and renewable energy innovations.
