The following safety recommendations are aimed at manufacturing operations utilizing urethane resins and hardeners (curatives). Polyurethane foam, which is essentially petroleum, is the predominant filling for baby mattresses and often contains dangerous chemical ingredients made of formaldehyde, benzene, toluene and other toxins. Polyurethane is a type of plastic that is produced by combining methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI) with polyols. Polyurethane was created as a replacement for rubber, a material that was hard to get hold of during the war. Polyurethane is a "polymer" that is a plastic that contains multiple units of carbamate (that's urethane in the previous chemical naming system).
