Da farko, muna bukatar mu fahimci ainihin bambanci tsakanin waɗannan abubuwa biyu. A taƙaice, polyurethane abu ne na roba wanda ya fi laushi, don haka ba shi da ƙaranci kuma yana da rikici. Wannan yana nufin cewa simintin gyare-gyare na polyurethane sun fi shuru a cikin aiki, amma ƙila ba za su iya jure lalacewa kamar simintin nailan ba.
