    aromatic or aliphatic diisocyanates. Aromatic diisocyanates contain benzene rings, which create polyurethanes that are generally tougher, stronger, and less costly than the aliphatics. The aromatics generally have tougher hard segments, which are more chemically resistant and give rise to higher

    materials ranging from soft to hard (72 Shore A to 84 Shore D). Medical-grade polyurethanes are designated aromatic or aliphatic, but there is not much difference between the two as far as having a high tensile strength (4,000 to 10,000 psi), high ultimate elongation (250 to 700%), good biocompatibility
