CORNING Eagle XG®

PROPERTIES
The glass composition includes no added heavy metals, reducing the environmental impact of manufacturing. EAGLE XG Slim Glass also features exceptional thinness, helping panel-makers reduce or completely avoid the potential environmental and health hazards associated with panel thinning.

BENEFITS
Corning® EAGLE XG® Slim Glass substrates enable panel manufacturers to innovate for thinner, lighter, and more environmentally conscious display panels. EAGLE XG Slim Glass delivers dimensional stability and exceptionally clean, smooth, flat surfaces – qualities essential to the successful manufacturing of LCD displays.

APPLICATIONS
Ideal for LCD and curved displays.

DIMENSIONS
Available thicknesses: 0.3 mm – 1.1 mm

IN-HOUSE INVENTORY AVAILABLE FOR ALL THICKNESSES

SCHOTT Borofloat 33®

PROPERTIES
BOROFLOAT™ flat glass has excellent optical characteristics because of the high quality resulting
from the float glass process. This opens up new applications for borosilicate flat glass which has proved itself over
time in laboratories, chemical processing plants, and in the home appliance and lighting industries.

BENEFITS
BOROFLOAT™ flat glass is highly resistant to water, neutral, acidic and saline solutions, as well as chlorine, bromine, iodine and organic substances. Even over long periods of time and at temperatures above 100°C, BOROFLOAT™ exceeds the chemical resistance of most metals and other materials. Maximum long-term operating temperature is 450°C.

APPLICATIONS
Precision engineering, optical applications, home appliances, environmental technology, sewage
treatment technology and lighting.

DIMENSIONS
Available thicknesses: 0.7 mm – 25.4 mm

CORNING Willow Glass®

PROPERTIES
Corning® Willow™ Glass is Corning’s ultra slim, fusion-formed, display-grade glass. Corning intends to provide sheets and rolls of 100 micron and 200 micron thin glass – about the thickness of a sheet of copy paper – up to one meter wide today and wider in the future.

BENEFITS
Corning® Willow™ Glass is a thin and flexible glass substrate that will enable low cost manufacturing of ultra-slim, curved and flexible displays, as well as touch sensors. It also has application opportunities outside of display, where its natural hermetic properties combine with its optical transmission qualities to make it appropriate for a host of barrier applications. Willow Glass combines the inherent benefits of glass – optical purity, thermal stability and an exceptionally clean, smooth and flat surface – with a mechanically bendable form factor.

For other barrier applications, Willow Glass’ hermetic properties, combined with its thinness, helps prevent moisture, oxygen, and other environmental elements from damaging appliances. Potential uses range from protecting sensitive electronics within a device to providing a barrier layer for the exterior surfaces of household appliances, such as refrigerators.

The thin and flexible characteristics of Willow Glass can enhance OLED lighting applications by enabling designers to create lighting panels and a wide range of lamp designs that rely on curved or flexible form factors.

APPLICATIONS
Ideal for ultra-slim, curved and flexible displays, as well as touch sensors and barrier applications.

DIMENSIONS
Available thicknesses: 100 and 200 micron

CORNING Gorilla Glass 3

PROPERTIES
Corning® Gorilla® Glass 3 with Native Damage Resistance™ 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 new core composition, this glass enables improved damage resistance and toughness by helping to prevent the deep chips and scratches that cause glass to break.

BENEFITS
Designed with superior surface quality, this glass has improved native damage resistance that enhances retained strength after use and provides high resistance to scratch and sharp-contact damage.

APPLICATIONS
Ideal protective cover for electronic displays in Smartphones, Laptop and Tablet Computer Screens, Mobile Devices, Touchscreen Devices, Optical Components, and High-strength Glass Articles

DIMENSIONS
Available thicknesses: 0.4 mm – 2.0 mm

SCHOTT D 263® T Eco Thin Glass

PROPERTIES
D 263® T eco thin glass is a clear borosilicate glass that has a high chemical resistance and is produced by a SCHOTT specific down-draw method. It is available in a variety of thicknesses ranging from 0.03 mm to 1.1 mm.

BENEFITS
Stable against sunlight and heat. Not permeable to humidity and flexibility similar to plastic. Reduced thickness and weight in mobile applications. No loss in image quality due to superior luminous transmittance.

APPLICATIONS
Resistive touch panel for built-in car navigation. Substrate for capacitive touch sensors, as well as IR cut-off filter for camera modules in cell phones.

DIMENSIONS
Available thicknesses: 0.21 mm – 1.1 mm

Soda Lime

PROPERTIES
Soda lime float glass is manufactured in a wide variety of sizes and thicknesses to 0.4 mm. The
manufacturing of thin and extra-thin glasses according to the float process guarantees optimal surface evenness,
minimal variation in thickness and, within a single batch of glass, lower thickness tolerances than those obtained
through any other manufacturing process.

BENEFITS
An affordable pliable solution that can be chemically strengthened.

APPLICATIONS
Optical substrates, displays for computers or electronic devices, special mirrors (cosmetic,
photographic, automotive), thin film coating substrates.

DIMENSIONS
Available thicknesses: 0.4 mm – 25 mm
