It is a polymer composed of oirganic units joined by carbamate links. There are 3 types of polyurethane depending of their properties.

The ones that are spongy and flexible.

Others that are soft and compact.

And finally the elastic and adhesive ones.

Polyurethane foaming by the chemical reaction of two components: Isocyanate ( the dark component in this video) and polyol containing chemical additives and blowing agents ( the clear component). The proportions and formulations of both products are defined according to the industrial application: flexible, semirrigid or rigid foams .
