Röhm Plexiglas® GS 0Z09 (209) Cast Acrylic (discontinued **)
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, Cast
Material Notes:	Description: PLEXIGLAS® GS cast acrylic has the following properties: absolutely colorless and clear break-resistant unequalled resistance to weathering and ageing high-quality surface and planarity; brilliant or satin (PLEXIGLAS SATINICE®) sheets, blocks, tubes, round and square rods 2 to 160 mm solid sheet / block thickness standard size up to 3050 x 2030 mm more than 50 standard colors good resistance to dilute acids limited resistance to organic solvents good resistance to alkalis very easy to work, similar to hardwood easy to thermoform over wide range of conditions easily and firmly bonded, e.g. with reaction adhesives (e.g. ACRIFIX® 190, 192) burns more or less like hardwood; very little smoke generation max. service temperature approx. 80 °C Specific Notes for this Material: UV-absorbing special grade with increased heat deflection temperature and better chemical resistance. Information provided by degussa. The former Evonik Methacrylates business has been sold to Röhm GmbH (Roehm).
