PU foam description:

Polyurethane foam is one of the four basic types of products that can be made from raw, liquid polyurethane. They are comprised of two chemicals which, when mixed and heated, form liquid polyurethane prior to being further processed. These chemicals are polyol, a type of complex alcohol, and diisocyanate, a petroleum byproduct that reacts strongly with alcohol. By combining the two, a stable long-chain molecule is formed. It's a polymer, or plastic, known as urethane.
