Röhm PLEXIGLAS® XT Clear 0A070 UV transmitting PMMA (discontinued **)
Categories:	Polymer; Thermoplastic; Acrylic (PMMA)
Material Notes:	The Product and its Benefits: PLEXIGLAS XT Clear 0A770, and extruded clear and highly UV-permeable acrylic (polymethyl methacrylate, PMMA), was specially developed as a cover material for sun bed canopies. This means that elements made from this material are used to cover lamps in the roof section of solaria, sun beds etc.; PLEXIGLAS® XT 0A770 is not designed for rests/supports or parts entering into contact with sun bed users. The UV transmission of this material even increases noticeably after a few hours’ exposure to UV radiation. PLEXIGLAS® XT 0A770 can be machined with ease, thermoformed, cold-curved and bonded, as well as screen-printed or coated. The strength values are the same as for the basic grades of PLEXIGLAS® XT. PLEXIGLAS® XT 0A770 does not become brittle or yellow even after prolonged exposure to UV radiation. The former Evonik Methacrylates business has been sold to Röhm GmbH (Roehm).
