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.
Polystyrene was discovered in 1839 by Eduard Simon, an apothecary from Berlin. [11] From storax, the resin of the Oriental sweetgum tree Liquidambar orientalis, he distilled an oily substance, that he named styrol, now called styrene.
Solid polymeric foam for packaging under the optical microscope. A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1]Examples include:

Polyurethane synthesis, wherein the urethane groups −NH−(C=O)−O− link the molecular units A kitchen sponge made of polyurethane foam . Polyurethane (/ ˌ p ɒ l i ˈ jʊər ə ˌ θ eɪ n,-j ʊəˈr ɛ θ eɪ n /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links.
The company was founded as Fagerdala World Foams in 1964 by father and son, Alf and Dag Landvik. [citation needed]The company’s initial products were Polyurethane mattresses and cushions, before expanding into other foam applications.
Robert A. Volz is credited with discovering the first process for making reticulated polyurethane foam in 1956 while working for the Scott Paper Company. [6] Production of reticulated polyurethane foam is a two-step process that begins with the creation of conventional (closed-cell) polyurethane foam, after which cell faces (or "windows") are removed.
