Buttercream Buttercream Buttercream is a type of icing or filling used either inside cakes, as a coating, or as decoration. Simple buttercream is made by creaming together fats (butter, margarine, or vegetable oil shortening) and powdered sugar to the desired consistency and lightness. Typically twice as much sugar as butter by weight is used. Flavorings, in the form of extracts and oils, may also be added. Some recipes call for cream, non-fat milk solids, flour, or meringue powder. There are two types of meringue-based buttercream: Italian and Swiss. The meringues must be cooled to room temperature in order not to melt
Foam rubber used for the formation of foam rubbers, after World War II styrene-butadiene rubber replaced many natural types of foam. Foam rubbers have been used commercially for a wide range of applications since around the 1940s. Polyether polyurethane rubber was discovered and patented in the 1950s by Charles C. Price. Currently, polyurethane-based foams make up over 90%, by weight, of the entire market for polyurethanes. The largest amount of polyurethane is used by these industries: construction, transportation, home furniture, noise and vibration reduction, and carpet. Construction uses 27% of polyurethane, and transportation uses 21%. Flexible foam is the leading material usage
