ArothaneTM ARP-W-G is medical grade aromatic polyether-based thermoplastic polyurethane (TPU) loaded with 40-60% Tungsten as radiopacifier. It exhibits exceptional radiopacity compared to Barium Sulfate especially for smalldimension or thin-walled devices. ARP-W-G is known for its small particle size, high fluidity, and good dispersion. It is typically a material choice for guidewire coating.
