Foam (material)

Foam is a material made of tiny interconnected bubbles of gas trapped within a solid or liquid matrix. It is commonly used for cushioning, insulation, or packaging due to its lightweight, compressible, and shock-absorbing properties. The structure of foam provides excellent thermal insulation and soundproofing, with variations in density and firmness depending on its intended application. Foams can be made from plastics, rubber, or other materials, and are widely found in items like mattresses, seat cushions, packaging materials, and building insulation. Their versatility arises from the ability to engineer their properties to suit specific needs.
