So What is Polyurethane Foam Anyway?


Short answer:

Polyurethane foam is made by mixing two liquids, a resin and an iso together, Usually referred to as part A and B. Once mixed there is a reaction, and the foam you are probably familiar with is formed. It comes in many shapes and sizes from light weight and flexible to rigid and heavy.

A little longer answer:

Polyurethane is a polymer composed of organic units joined by urethane links. Most polyurethanes are thermosetting polymers that do not melt when heated.

Polyurethane is most commonly formed by reacting a polyisocyanate with a polyol. Both the isocyanates and polyols used to make polyurethanes contain, on average, two or more functional groups per molecule.

Well Is It Safe?

Short answer:

Yes, it is safe.

A little longer answer:

Once the polyurethane is mixed and the foam is formed it is chemically inert. No exposure limits have been established in the U.S. by OSHA (Occupational Safety and Health Administration) or ACGIH (American Conference of Governmental Industrial Hygienists) nor is it regulated by OSHA for carcinogenicity.

That’s Good to Know But What is a Carcinogen?
A carcinogen is any substance that is an agent directly involved in causing cancer.  

Well, I’ve Never Even Heard of Polyurethane Before.
Polyurethanes are all around you. It would be a challenge to get away from them.

Here are a few things that make excellent use of polyurethanes.

This list could virtually go on for days and as you will see it would be hard to escape polyurethane and most importantly that it is safe to use in your home.
