Polyurethane foam

Polyurethane foams are widely utilized polymer materials formulated from isocyanate and polyol. Following the reaction of these chemicals, they swell into a high-volume foam that solidifies ultimately. Polyurethane foams have use in a variety of industries, including construction, automotive, refrigeration, packaging, and furniture. Polyurethane foams are classified as soft or hard depending on their density, open or closed cell structure, and application.
