An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.
Foam rubber was first made in 1929, by E. A. Murphy [2] and Eric Owen, two research chemists at Dunlop Rubber, who used whipped latex. In 1937, isocyanate-based materials were first used to make foam rubber. After World War II, styrene-butadiene rubber replaced many natural types of foam. Foam rubber has been used commercially for a wide range ...
To create foam latex, a liquid latex base is mixed with various additives and whipped into a foam, then poured or injected into a mold and baked in an oven to cure.The main components of foam latex are the latex base, a foaming agent (to help it whip into a froth), a gelling agent (to convert the liquid foam into a gel), and a curing agent (to turn the gelled foam latex into a solid when baked).
The development of synthetic-enzyme based foaming agents; foam stability enhancing admixtures; and specialized foam generating, mixing, and pumping equipment has improved the stability of the foam and hence foam concrete, making it possible to manufacture as light as 75 kg/m 3 density, a density that is just 7.5% of water.

It was found that on average silver nanofoams can maintain over 90% FECO in a wide potential window (−0.5 to −1.2 VRHE), enabling the maximum CO selective current density of 33 mA cm−2 and the mass activity of 23.5 A gAg−1, which are the highest values among recently reported metal foam-based electrocatalysts.
