Momentive and Lee&Lee Collaborate on LED Lens Applications for Advanced Flat-Panel TV Technology

Momentive's Silopren* LSR 7000 Series Can Help Improve Performance and Durability of
LED Lens Parts for LED-Backlit LCD TVs

ALBANY, N.Y., November 2, 2010 - Momentive Performance Materials, a global leader in specialty chemicals and materials, has collaborated with Lee&Lee Hi-Tech Co., a leading manufacturer specializing in liquid silicone rubber (LSR) injection molding, to develop light-emitting diodes (LED) lens parts for flat-panel, liquid crystal display (LCD) TVs, using Momentive's Silopren* LSR 7000 Series.

LSR 7000 is a family of highly transparent liquid silicone rubbers that has earned industry recognition for outstanding clarity, efficient and economical manufacturing process, and ability to achieve highly complex optical components that surpass those made with traditional thermoplastic materials or glass. The combination of superior optical properties with the processing and productivity advantages of an addition-cured, platinum-catalyzed LSR makes the LSR 7000 series an excellent candidate to consider for applications requiring enhanced optical transparency. Also, due to the high temperature stability of silicone elastomers, the LSR 7000 series may be considered for applications where enhanced optical transparency is needed and potential stress cracking of thermoplastics is of concern.

"Our collaboration with Momentive has allowed us to establish an optimized process for producing more than 100 million lens units per month for LED-LCD backlight units," said Lee Yong-Kwon, President of Lee&Lee. "Using LSR 7000 in the injection molding process has more than met our expectations in material performance, process simplicity and quality consistency."

"We are excited about working with Lee&Lee to enhance the overall performance of LCD TVs that use an LED backlight instead of a conventional fluorescent one and to be a part of this new trend in flat-panel technology," said Holger Albrecht, Global Marketing Director, Consumer at Momentive. "Lens parts made from LSR 7000 have been repeatedly tested for durability and performance while exposed to high heat and humidity over long periods of time, and we are pleased with the results."
