Durathane™ ALC-B20 series products are medical grade aliphatic polycarbonate-based thermoplastic polyurethanes (TPU) loaded with 20% Barium Sulfate as radiopacifier. They exhibit excellent radiopacity and can be color-matched while retaining traits of clear grade ALC including the superior biocompatibility and mechanical properties as well as excellent resistance to oxidation, chemical, and hydrolysis. Due to the chemical structure, the aliphatic nature of ALC-B20 series products makes them more light-stable and bio-stable than the aromatic TPUs. These products can be injection molded and extruded.
