WebA foam is commonly defined as a dispersion of gas bubbles in a liquid. In a “solid foam” the liquid has changed into a gel or a solid phase after making the dispersion. The volume … Webreaction responsible for foam formation. Although several organometallic compounds or salts may be used as catalysts in the production of polyurethanes, many polyurethane manufacturers use either tertiary aliphatic amines or alkanolamines. Amine catalysts are typically 0.1 to 5.0 percent of a polyurethane formulation.,668( $; ì -8/< Foams are materials formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Soap foams are also known as suds. Solid foams can be closed … See more A foam is, in many cases, a multi-scale system. One scale is the bubble: material foams are typically disordered and have a variety of bubble sizes. At larger sizes, the study of idealized foams is … See more Stabilization The stabilization of a foam is caused by van der Waals forces between the molecules in the foam, electrical double layers See more Liquid foams Liquid foams can be used in fire retardant foam, such as those that are used in extinguishing fires, especially oil fires.
