Momentive Introduces Clear LSR Products

Momentive Performance Materials (www.momentive.com) recently introduced the breakthrough LSR7000 series, a family of highly transparent liquid silicone rubbers (LSR). Combining typically 98 percent transparency with the unique processing and productivity advantages of an addition-cured, platinum-catalyzed LSR, the LSR7000 series is an excellent candidate to consider for outstanding optical characteristics and increased design flexibility. These features potentially enable customers to reduce manufacturing and assembly cycle times for complex parts.

"By offering high transparency, high elasticity and easy processing, the LSR7000 series may help designers and manufacturers to effectively address many of the toughest design challenges they face,” said Yang Nuo, Pacific electronics marketing manager, Momentive. “This material is an excellent example of our strategic focus: we combine our close customer collaboration with our leading research and development capabilities, resulting in quick response to complex industrial needs. We are excited about this technology, as it may provide a new elastomeric solution for a broad range of applications where higher transparency is desirable.”

The LSR 7000 family includes products ranging in 60 to 80 Shore A hardness. Recent innovation in optical systems, light-guide applications and mobile phones have increasingly seen liquid silicone rubbers replace materials such as transparent polycarbonate and polymethyl methacrylate (PMMA) in new applications, due to the unique processing and productivity advantages of LSR.

In China, Momentive has cooperated with Sunrex, a leading input device manufacturer, to apply the LSR7000 series to light guide film for commercial production. “By combining our proprietary technology with the super transparency of LSR7000, we have been able to successfully develop silicone light guide film for use in new mobile equipment,” said Liu Dianshan, director of the Sunrex facility in Suzhou. “We are now cooperating on a long-term basis with Momentive to develop new, flexible applications for smart 3D light guide film.”

Momentive will be showcasing the LSR7000 series at the Fakuma 2008 trade fair along with other innovations in silicone elastomers, RTVs and hardcoats.
