Description: PLEXIGLAS® zk40is impact modified molding compounds based on polymethyl methacrylate (PMMA). The grades of the zk series are the classical impact-modified PLEXIGLAS® molding compounds. (zk30 and zk50)PLEXIGLAS® zk molding compounds are particularly suitable for injection molding. They can, however, also be used for profile extrusion or coextrusion. Uses of PLEXIGLAS® zk molding compound: lighting fixtures, writing and drawing utensils, domestic appliances and sanitary ware.Information provided by degussa.
