Foam is nothing more and nothing less than a material obtained through chemical reactions, in this case between a polyol and an isocyanate.
Only within the foams we can find several variations. For example, polyurethane foams (which are the ones you will find here at Eurospuma) are divided into three groups: rigid, flexible, and moulded. They can either be soft or hard, with varying degrees of durability, and produced in different colours or infused with additives that give them special characteristics.
