| Plexiglas® HFI7G is an impact modified thermoplastic acrylic resin formulated for injection molding and extrusion applications.This grade is formulated for approved medical applications and has improved gamma resistance compared to HFI7. It is heat resistant, has high melt flow and provides 7 times the impact resistance of standard acrylics while maintaining excellent optical properties. 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. Supplemental moldflow simulation data is available. |
