| Plexiglas® DR® is an impact modified thermoplastic acrylic resin formulated for injection molding and extrusion applications. It is a heat resistant resin with minimal edge color and provides 10 times the impact resistance of standard acrylics. It is an all-acrylic resin that combines the toughness associated with other impact plastics and the outstanding transparency and UV resistance of conventional acrylic materials. Moldflow simulation data is available.&& |
