Röhm Plexiglas® 99560 MR2R Superclear Extruded, Mar Resistant PMMA Sheet (discontinued **)
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, Extruded
Material Notes:	Description: PLEXIGLAS® Superclear 99560 MR2R is an extruded PMMA sheet with a mar resistant coating on both surfaces. The product has been developed for applications with highest demands on optical and surface quality. It has no observable haze, a very smooth surface, no light absorption and a very tight thickness tolerance. Information provided by degussa. The former Evonik Methacrylates business has been sold to Röhm GmbH (Roehm).
