Believe it or not, one of the most widely used materials in the world is foam. It has a wide variety of applications ranging from packaging, cushioning, insulation, sound proofing and so much more. Given the wide usage of foam, then perhaps it is time to learn more about our little polyurethane friend?

Foam is usually made of polyurethane and depending on the intended application, can contain infusion of other materials such as charcoal or gas mixtures. Even the composition of the polyurethane itself can differ for different foam applications. Generally speaking though, there are two classifications of foam based on construction; open cell foam and closed cell foam.

Open cell foam is what is generally used for cushions and packaging because they are softer than close cell foam. It is called open cell because if you look at it, the construction of the foam has. This open construction makes it more flexible and more comfortable for cushion applications. The downside to open cell foam though is that they are less rigid and are not as good as closed cell foam for insulation.

Closed cell foam are the tougher lot in the world of foams, they are generally used for home insulation and soundproofing. They are called closed cell because they do not have pores and are rigid. The downside to closed cell is that it can’t be used for cushions.
