ArothaneTM ARP-B40 is medical grade aromatic polyether-based thermoplastic polyurethane (TPU) loaded with 40% Barium Sulfate as radiopacifier. It exhibits better radiopacity than ARP-B20 and can be color-matched while retaining the superior mechanical properties, excellent hydrolytic resistance, oxidative stability, chemical resistance and biocompatibility of clear grade ARP. It can be injection molded and extruded.
