Product catalog summary
Introduction
Corning® Willow™ Glass is a flexible glass product that maintains the superior attributes of traditional glass while being thin enough to bend. It is designed to enable the production of thinner, lighter, and potentially flexible electronic devices, offering high performance at a reduced cost.

Specifications
  • Thickness: Comparable to a sheet of copy paper, available in 0.05 mm, 0.1 mm, and 0.2 mm thicknesses.
  • Composition: Alkali-free Borosilicate.
  • Sizes: Sheets available in sizes less than 500 x 500 mm; rolls available in widths up to 1 meter and lengths up to 300 meters.
  • Packaging: Options include edge tab, leader, trailer, and 8.4” OD spools, with flat box and interleaf packaging.

Optical and Mechanical Properties
  • Optical Transmission: Varies with wavelength and thickness, with higher transmission at thinner dimensions.
  • Bend Stress and Radius: Demonstrates flexibility with varying bend radii depending on thickness.

Sample Characteristics
  • Density: 2.3 - 2.5 g/cc.
  • Poisson Ratio: 0.20 - 0.25.
  • Strain Point: 650 - 700°C.
  • Annealing Point: 700 - 750°C.
  • Dielectric Constant: 5 - 6.
  • Surface Roughness: Ra < 0.5 nm, Rpv < 20 nm.
  • CTE (Coefficient of Thermal Expansion): 3 - 5 ppm/°C.
  • Young’s Modulus: 70 - 80 GPa.

Availability
Sample quantities of Willow Glass are available, with specific sizes and thicknesses released in different quarters from 2012 to 2014.

Fact Sheet The future is flexible: Corning® Willow Glass TM At roughly the same thickness as a sheet of copy paper, Corning® WillowTM 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. It will enable thinner, lighter, and potentially flexible electronic devices, that deliver high performance at a lower cost. Edge tab enables practical use of Willow Glass in roll-to-roll processing.
