New LSR reported to enable breakthroughs in LED lighting technology

WATERFORD, N.Y—Momentive Performance Materials Inc. recently unveiled a next-generation, ultra-clear liquid silicone rubber (LSR) that combines LSR technology with a specialty polymer technology. The result enables luminaires to be equipped with high flame resistance above the UL 94 flame class rating of V-1.

“By combining improved flame resistance with good optical clarity and long-term color stability in harsh conditions, this next-generation grade is an excellent material to consider for flame-resistance applications, such as lenses, light guides, and other optical parts in outdoor lighting,” said Hee-Seok, Hwang, senior global project manager, in a press release.

By combining improved flame resistance with optical clarity and long-term color stability in harsh conditions, this next-generation grade is an excellent material to consider for flame-resistance applications such as lenses, light guides, and other optical parts in outdoor lighting, Hwang said in the release.

Momentive (www.momentive.com) has been working with global experts in the lighting industry such as Khatod, a major manufacturer of optical products.

“This application is very technical. Khatod was searching for a material able to comply with the various optical, mechanical, and molding process requirements needed for the realization of unique, high-performance optics,” said Dieter Wrobel, corporate fellow at Momentive, in the release. “After in-depth analysis and numerous laboratory tests, Khatod determined that our Ultra Clear Silopren LSR 7000 liquid silicone rubber series was an ideal match for their application.”

Khatod recently utilized Momentive’s next-generation ultra-clear LSR in its SIO3 Silicone Lenses, said to be “a breakthrough in LED lighting technology” and “the world’s first range of free form lenses made of LSR optimized for the most popular HB and COB LEDs,” according to the release.

“Khatod is a real innovator in the LED lighting industry,” said Giuseppe Vasta, president of Khatod Optoelectronic, in the release. “Our SIO3 lenses boast cutting-edge engineering and exclusive cold runner-based LSR injection molding process specially customized by Khatod for optical silicone processing. This innovative construction process preserves and enhances the typical characteristics of silicone and makes the lenses excellent for any application in LED lighting requiring excellent lighting performance, as well as a robust, long life, safe, and reliable service.”

Khatod’s SIO3 Silicone lenses, formulated with Momentive’s next generation Silopren LSR 7000 series, recently won LED magazine’s SSL Enabling Technologies Sapphire Award, which highlighted “the most inspirational and innovative products in the LED marketplace,” according to the release.
