Durathane™ ALC series products are medical grade aliphatic polycarbonate-based thermoplastic polyurethanes (TPUs).They exhibit superior mechanical properties, excellent hydrolytic resistance, oxidative stability, chemical resistance and biocompatibility. Color-matching is available. These products can be injection molded and extruded. Due to the chemical structure, the aliphatic nature of ALC series products makes them more light-stable and bio-stable than the aromatic TPUs.
