Why I hate polyurethanes

I can’t imagine a more nondescript name for a polymer.  (To be fair, polyureas, polyesters and all other condensation polymer suffer the same flaw, except that the options for the intra-urethane segments of a polyurethane are much more diverse than for any of these others.) I am constantly barraged by coworkers and clients bringing me a sample of a “polyurethane” highly expecting me to know exactly what it is. You can make bowling balls, sponges, pressure sensitive adhesives and much, much more from polyurethanes: how am I suppose to know the exact chemistry when all you can tell me is it is a polyurethane?
