Q:What Is Polyurethane?
A:  Polyurethane is a synthetic material that is used in various applications in nearly every field imaginable. It is renowned for its durability and flexibility and can be produced in a number of different forms based on what it will be used for. Everything from airplane wings to tires can be made with polyurethane.
·                                  
Q: Polyurethane Identification
A:   Polyurethane is identified as a polymer, which is basically a string of smaller molecules known as monomers. In this case, it is a string of urethane. An entire polyurethane chain consists of nitrogen, carbon and oxygen atoms double-bonded to a hydroxyl group, which is also known as an alcohol and is a bonded molecule of oxygen and hydrogen. When various other elements are added to this basic chain, the polyurethane changes, sometimes becoming a rubbery solid, liquid or even a foam.
 

Q: Polyurethane Features

A:  Polyurethane can be manufactured synthetically to have a number of different features, depending on the specific molecules that are added to its basic string of urethane molecules. Some of the more sought-after features of polyurethane are its elasticity and durability. This makes it popular for use with tires and other rubber devices that need to be strong and bendable. Polyurethane can also be made into a squishy, foam-like substance or a substance similar to glue, with the same bonding ability.
Q  Polyurethane Function
A:  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.
 

Q: Warning

A: 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.
 

Q:Polyurethane Benefits

A: 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.
