Corning® 7740

Description

Corning® 7740 is a clear, colorless borosilicate glass by Corning with very similar properties to Borofloat® 33. To produce this glass, particles of silica sand, boric acid, fluxes and stabilizers mix together. Next, a furnace heats the mixture at 1600°C for up to 24 hours to remove any bubbles and imperfections. The glass is formed in blocks, as opposed to sheets, so they must be sliced, ground, lapped, and polished before being used.

Properties

• Good thermal shock resistance
• high temperature resistance
• low thermal expansion – same as silicon
• high acid resistance
• great optical transmission over a wide range of wavelengths, from ultraviolet to infrared.

Applications

Due to their similarities, these wafers have many of the same applications and are interchangeable with Borofloat® substrates. Some common uses for these substrates are LCD displays, dielectric coating, sensor substrates, neutron absorber, and in high temperature environments.

Corning® Willow Glass™

Description

Willow Glass™ by Corning is ultra-thin, lightweight & conformable. It is manufactured at thicknesses that create unique properties such as the ability to be flexible and bendable. Additionally, Willow Glass laminage is Fusion-formed for an incredibly smooth, flat surface which is virtually free of defects.

Willow Glass™ can increase the durability of the substrate, adding a scratch-resistant, easy to clean, beautiful surface and is a perfect hermetic barrier that protects sensitive materials from moisture, oxygen, and staining.

Properties

• Efficient, low cost Roll-to-Roll Manufacturing
• 100 and 200 micron 1.3 meters wide and upto 300 meters in length.
• Improved scratch, chemical, and damage resistance versus plastic
• Superior surface with the natural beauty of glass
• Cutting and fabrication on-site using readily available tools
• Color-free transparency to the substrate below
• Excellent hermeticity and barrier properties

Dimensional Specifications

Importance of Orientation

If your intended application for Willow Glass™ involves bending of the substrate, it is essential to understand Compression vs. Tension and orient your part accordingly.

Though Coresix has established and regularly tests our scribe process to maximize edge quality and resulting strength, bending the glass toward the scribe side, thereby “compressing” the micro-fractures created by the scribe, will result in the strongest condition.

Coresix identifies the compres-sion side as part of our stan-dard packaging procedure.

Willow Glass Cleaning

Standard Cleanliness

Willow Glass™ is produced in a continuous strip and rolled onto a spool at the production line. Coresix maintains this pristine condition through strictly controlled handling and processing. For best cost efficiency, we pack most products directly from the cutting line.

Ultrasonic Cleaning

For cleanliness critical applications, Coresix has the capability of ultrasonically cleaning Willow Glass as thin as 100μm and as large as 500mm diagonal

Willow Glass Packaging

Small Format

For sizes up to 500mm Square, parts are “stacked” with Tyvek paper interleaf, shrink-wrapped, and placed in a cardboard box with a protective liner.

Large Format

Sizes exceeding 500mm are “stacked” with Tyvek paper interleaf in a custom-sized wood crate with a protective liner.

Cleanliness Critical

For applications requiring a minimize-tion of particulate, parts are packed using additional plastic sheet liner to reduce in-transit contamination.

Corning Lotus NXTTM High Performance LCD & OLED Display Glass

With Corning Lotus NXT, Corning has effectively achieved the display industry’s optimized manufacturing solution for the growing OLED market.

Lotus NXT Glass is Corning’s newest edition to their specialty glass platform. It performs fantastically in low-temperature poly-silicon (LTPS) and oxide thin-film transistor (TFT) backplane manufacturing processes.

A third-generation glass composition for high-performance displays, Lotus NXT Glass provides industry-leading levels of low total pitch variation.

What does Total Pitch Variation mean?

TPV or Total Pitch Variation is a metric that is essential to the manufacturing of LCD and OLCD Display glass. Lotus NXT Glass outperforms incumbent products using this TPV metric by up to 60 percent.

Unpredictable movement results in yield loss. If you can predict the amount the glass shifts, then you can account for that movement with every new glass substrate.

Total Pitch = distance features move during processing within a single glass sheet.

Variation = deviation from predictable movement between multiple glass sheets.

This is great news for panel makers, because it enables Corning to provide a much better product th higher yields, and better etching performance.

Ultimately consumers benefit greatly with higher resolution, brighter displays with lower power consumption and longer battery life.

What's the difference in LED, LCD and OLED Displays

OLED: Organic Light Emitting Diode. OLED displays are solid-state devices composed of thin films of organic molecules that create light with the application of electricity.

OLED displays can be curved, thinner, or have narrower bezels, no bezels or flex and bend. An OLED display is a great solution with higher resolution, superior response time and latency.

OLEDs can provide brighter, crisper displays on electronic devices and use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs).

LED: Light-emitting Diodes. LED displays are flat panel displays that use an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards.

LCD: Liquid-crystal display. LCD displays are an always-on backlight projects light through a liquid crystal, sandwiched between two pieces of glass. When the liquid crystal is excited by an electrical current, it lets the light of an individual pixel pass through like a shutter.

Soda Lime

Description

Soda Lime glass, also called soda–lime–silica glass, is the most prevalent type of glass, used for windowpanes and glass containers (bottles and jars) for beverages, food, and some commodity items. Soda Lime glass accounts for about 90% of manufactured glass.

The mixture in Borosilicate glass binds all the chemicals more tightly together, leading to a much higher melting point. Borosilicate glass has a higher proportion of silicone dioxide than Soda Lime glass (80.6% in Borosilicate glass and 69% in Soda-lime glass).

Properties

• Relatively Inexpensive
• Chemically Stable
• Reasonably Hard
• Extremely Workable

Applications

Soda lime glass is produced on a large scale and used for bottles, drinking glasses, and windows. Its light transmission properties, as well as low melting temperature, make it suitable for use as window glass. Its smooth and non-reactive surface makes it excellent as containers for food and drinks.

Pilkington Optiwhite™

Description

Pilkington Optiwhite™ is a low-iron extra clear float glass with very high light transmission. It is practically colourless, and the green cast inherent to other glasses is not present. It is therefore ideal for use where glass edges are visible or where a neutral colour is desired. As its light transmission is higher than clear float glass, it is perfect for applications where transparency and purity of colour are desired.

Properties

• High light transmission for outstanding visual clarity when an unrestricted view is required
• Purity of colour with minimum colour cast when viewing through the glass, ensuring a truer representation of the designer’s vision
• High solar heat transmittance providing passive solar gain to allow more heat through, which can save costs on energy bills during the winter
• Flexibility of application
• Can be toughened or laminated for safety and security
• Can be combined with other products from the Pilkington Range to provide
  additional benefits

Applications

One of the most attractive features of Pilkington Optiwhite™ is its ability to achieve greater brilliance and transparency, allowing a clear and true representation of colours when viewed through the glass. These same qualities also allow for great interior daylight, which no doubt explains why Pilkington Optiwhite™ is the product of choice for architects for buildings where transparency and brightness are of paramount importance.

Thanks to these and the many other benefits that Pilkington Optiwhite™ brings to exterior glazing, it is the perfect choice for facades.
