Röhm Plexiglas® df22 zk6BR Molding Compound
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, General Purpose, Molded
Material Notes:	Description: Impact-modified PLEXIGLAS® df22 zk6BR and PLEXIGLAS® df23 zk6BR molding compounds based on PLEXIGLAS® zk6BR are characterized by diffuse scattering of light. Besides showing the familiar properties of basic molding compound PLEXIGLAS® zk, such as good impact strength good weatherability high surface hardness and scratch resistance PLEXIGLAS® df22 zk6BR and PLEXIGLAS® df23 zk6BR are special in that they combine good diffusing power with excellent light transmission and satin surfaces can be obtained by variation of the extrusion parameters. PLEXIGLAS df molding compounds are the optimal choice, when a combination of high light scattering and excellent light transmission is required. Both, PLEXIGLAS df22 zk6BR and PLEXIGLAS df23 zk6BR are well designed for lamp covers, projected areas and similar applications. Information provided by degussa. The former Evonik Methacrylates business has been sold to Röhm GmbH (Roehm).
