“Momentive is a pioneer in LSR technology and we are now bringing our expertise to ultra-clear LSR solutions for high wattage LED lighting applications,” said Hee-Seok, Hwang, Senior Global Project Manager. “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.”

Momentive has been working with global experts in the lighting industry such as Khatod, a leading manufacturer of optical solutions. “This application is very technical. Khatod was searching for a material able to comply with the various optical, mechanical and moulding process requirements needed for the realization of unique, high-performance optics,” said Dieter Wrobel, Corporate Fellow at Momentive. “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. These lenses are a breakthrough in LED lighting technology and are the world’s first range of free form lenses made of LSR optimized for the most popular HB and COB LEDs. “Khatod is a real innovator in the LED lighting industry,” said Giuseppe Vasta, President of Khatod Optoelectronic. “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 Magazines’ SSL Enabling Technologies Sapphire Award, which highlighted the most inspirational and innovative products in the LED marketplace.
