Polymer Foam is a lightweight, porous material made by incorporating gas or air into a polymer matrix during the manufacturing process, resulting in a structure with a high volume of air pockets. Depending on the type of polymer and foaming method used, polymer foams can be classified as either open-cell or closed-cell foams, each offering distinct properties. Open-cell foams are softer and more flexible, allowing air and liquids to pass through, while closed-cell foams are denser, providing better insulation and moisture resistance. Polymer foams are widely used across industries, including packaging, construction, automotive, and consumer goods, due to their excellent cushioning, thermal insulation, and impact absorption properties. Common examples include polyurethane foam, polystyrene foam, and polyethylene foam, each tailored for specific applications.
