Momentive launches high transparency silicone elastomer

ERJ staff report (DS)

Leverkusen, Germany -- Momentive Performance Materials has launched a line of highly transparent liquid silicon rubber (LSR) for innovative optical applications. These new materials are characterised by their high transparency (up to 95%), low opaqueness and excellent physical stability. Therefore the material is of interest for the manufacture of ancillary LED lenses in the automotive applications.

The LSR 7000 series was originally developed for the manufacture of light conductor systems for mobile telephone backlighting. The qualities of this material have been put to the test and have proven themselves a million times over in this area of application. The LSR 7000 series is commercially available in a hardness range from 60-80 Shore A. Furthermore, an ultra-soft 5 Shore A version has recently become available.
