Function
Polyurethane is used in so many different fields and in so many different forms that it is one of the most used synthetic materials. Look around your house, and you will be able to find many things that are made of polyurethane. Much of the firmer rubber used for various reasons is polyurethane, and because as an adhesive it is water and heat resistant, it's used in outdoor and exceptionally hot areas. It is also used in walls as extra padding, and in foam form for soundproofing.
Warning
For the most part, polyurethane is not a dangerous substance--which is why there is no limit on exposure to it. However, there are times where it can let off harmful chemicals, including carbon monoxide and other hazardous fumes. This is generally when polyurethane is heated to over 200 degrees C. For this reason, handling this polymer at high temperatures should be done with gloves and a personal breathing apparatus.
Benefits
One of the major benefits of polyurethane is its resistance to heat and flames. Using the substance means that it will offer protection from this, which makes it particularly beneficial in the home and in making important substances and materials. It is often used as a coat for wood, plastic or other substances because of this protective property.
