| Plexiglas® V045i is a lightly impact modified thermoplastic acrylic resin formulated for extrusion applications. It is characterized by its chemical and heat resistance as well a high melt flow. It is a tougher resin than Plexiglas® V045 allowing improved fabrication. It offers an excellent balance between melt flow and increased resistance to breakage, while providing weatherability superior to that provided by other high-impact plastics.&& |
