Polyurethane flammability
Polyurethane is a “polymer” that is a plastic that contains multiple units of carbamate (that’s urethane in the previous chemical naming system). It’s easy to produce and can be made from a variety of monomers (individual urethane units) and as such there is no single plastic called “polyurethane”, instead it refers to … See more This is a complex question because while most pure polyurethanes are flammable, some are not, and you can add flame-retardant chemicals to polyurethane to change this property. … See more “Environmentally friendly” is a very big topic, but it’s fair to say that as plastics go, polyurethane is more eco-friendly than most.
