Headquartered in Lakewood, OH, USA, the company specializes in developing custom thermal solutions that leverage the unique thermal properties of natural graphite.
Under the eGRAF® product line, GrafTech manufactures a wide range of natural graphite thermal solutions, including heat spreaders, thermal interface materials, and heat sinks. Committed to the development of new thermal management technology, eGRAF® products have earned broad recognition in the market, winning R&D 100 awards in 2003 and 2004, and Frost and Sullivan’s Excellence in Technology Award in 2005.
Backed by over a dozen U.S. and global patents, eGRAF® product technology is driven by a world-class team of over 20 scientists, engineers and researchers.
Every day, eGRAF® products answer thermal design questions from industry-leading companies around the world:
• What challenges do you face in designing next-generation products?
• Are you constrained by weight limitations, space limitations or temperature limitations?
• Do your customers demand better performance, extended product life expectancy and increased product reliability?
• What thermal issues are you constantly trying to overcome?
eGRAF® products have differentiated product designs and secured competitive advantage. Each design has been proven to have thermal benefits that outperform other materials:
• Reduce screen temperature in plasma display panel televisions
• Reduce touch temperature in cell phones
• Provide much needed weight savings in the world’s lightest laptop computers
• Eliminate the need for cooling fans
• Shield temperature-sensitive components from excessive heat
As market demands change and evolve, eGRAF® products continue to exceed expectations. In a few short years, award-winning eGRAF® SPREADERSHIELD™ products have driven natural graphite’s in-plane thermal conductivity from 200 to 500 W/mK—even as market adoption is in the early growth stages.
With a knowledge base of over 100 years in bringing innovative carbon and graphite-based products to market, GrafTech provides solutions within the consumer and industrial electronics, military, telecommunications and transportation industries.
eGRAF® SPREADERSHIELD™ Products
SPREADERSHIELD™ material can be die-cut, laminated with plastics, metals or adhesives, and is flexible enough to conform to product contours. Many consumer and automotive electronic devices have utilized SPREADERSHIELD products, such as cell phones, laptop and ruggedized computers, handheld gaming devices, batteries, projectors and set-top boxes.
eGRAF® zSPREADER™ Products
High-power LEDs are increasingly being used in flat panel displays, mini-projectors, general illumination, automotive, traffic signals and architectural lighting. Although high-power LEDs are rapidly becoming the industry standard, current options for heat dissipation have fallen behind this new technology. As a result, users of high-power LEDs face a range of problems, including:
• Insufficient light output
• Poor reliability
• Undesirable lumen maintenance
• Excessive power consumption
• High lifetime cost.
zSPREADER™ products are manufactured through a unique riveting process, where each metal via is inserted through SPREADERSHIELD™ natural graphite at a 90-degree angle, creating a 3-dimensional heat spreading solution. Each metal via is in direct contact with a heat source, conducting heat rapidly into the SPREADERSHIELD™ material.
With a lower thermal resistance and lighter weight than aluminum or copper, zSPREADER™ designs are quickly becoming the newest alternative technology to cooling high-power LEDs.
