Liquid silicone rubbers of the LUMISIL® LR 7600 series are paste-like, two component compounds with short curing times. The vulcanizates are noted for their very high optical transparency and excellent mechanical and electrical properties.
Properties
The products can be used at temperatures down to -55 °C and even above +150 °C. The outstanding optical transparency extends over a broad range of the visible spectrum and exceeds the transparency of polycarbonate or polymethylmethacrylate. The refractive index nD25 is in the range of 1.41.
In contrast to standard ELASTOSIL® LR grades, the hardness in the product name of LUMISIL® LR 7600/60 A/B reflects the hardness of vulcanized articles in the non-post cured state. Depending on the injection molding parameters, the geometry of the final parts and the post curing conditions, hardness increases after post curing in the range of 5 to 12 points.
Application
These grades are particularly suitable for the economical production of large series of injection molded articles with excellent optical transparency. Parts made from LUMISIL® LR 7600/60 A/B can be used for technical applications. If these articles are also suitable for use in conjunction with foodstuffs is currently under evaluation.
