Röhm Plexiglas® XT Grey 99561 RP Extruded Acrylic Sheet  (discontinued **)
Categories: Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, Extruded

Material Notes: Description: PLEXIGLAS® XT Grey 99561 RP is an extruded acrylic sheet with embedded micro lenses that is developed to act as rear projection screen. The integrated micro lenses perform an excellent image formation without hot spot. The neutral grey color generates high contrast without color shifts. The antiglare surface is insensible against scratches and therefore particularly suitable for rough environments.
