Glass LED technology poses challenge for plastics

Post Time:Oct 09,2009Classify:Industry NewsView:391

Even as plastics continue their assault on glass and other established materials in a variety of applications, the suppliers and processors of those same materials naturally are fighting back, as in the case of a new technology for glass LEDs.

The technology is being marketed by a newly formed joint venture, Evonik Cristal Materials Corp., between Evonik Industries AG (Essen, Germany) and Taipei, Taiwan-based Cristal Materials Corp., a company formed in 2006 for the production of LEDs.

The two expect 20%/yr or greater demand growth for glass light emitting diode (LED) lenses made using Evonik’s SiVARA-brand technology, which makes it possible to manufacture glass lenses in any shape. This design flexibility has of course always been one of plastics’ big drawing cards over glass.
"The LED market will see many new areas of application open up. Evonik Cristal Materials Corp. will help its customers develop new technologies faster, technologies such as UV LEDs to sterilize water, LEDs in automobiles, and LEDs for general lighting," said Patrik Wohlhauser, chairman of Evonik Degussa GmbH's management board. The lenses produced by the joint venture will be sold to LED manufacturers.

LEDs are increasingly used in many different lighting applications as they last longer and are brighter than other light sources. Plastics have made inroads into the LED market and no doubt will continue doing so, but with the advent of this glass-forming technology the competitive barrier to entry has been raised a bit.
