What is Polyurethane Flexible Foam?

Before we delve into the specifics of ZF-22, it’s essential to understand what polyurethane flexible foam is and how it’s made. Polyurethane foam is a type of plastic that is created by reacting two primary components: a polyol (a type of alcohol) and an isocyanate (a highly reactive organic compound). When these two substances are mixed, they undergo a chemical reaction that forms a polymer network, resulting in a lightweight, porous material with excellent cushioning properties.

The flexibility of PU foam comes from its open-cell structure, which allows air to flow through the foam, making it soft and pliable. This structure also contributes to the foam’s ability to recover its shape after being compressed, a property known as "resilience." Depending on the formulation, PU foam can be made in a wide range of densities, from ultra-light foams used in packaging to high-density foams used in seating and mattresses.
