Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde . [ 1 ]
A "Mr. Clean Magic Eraser" brand sponge, made from melamine foam. Melamine foam is a foam-like material consisting of a melamine-formaldehyde condensate. It is the active component of a number of abrasive cleaner sponges, notably the Magic Eraser. It is also used as thermal insulation and as a soundproofing material.
Melamine also is used in the fabrication of melamine polysulfonate, used as a superplasticizer for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as a cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during handling and pouring. It ...
In approximate order of decreasing consumption, products generated from formaldehyde include urea formaldehyde resin, melamine resin, phenol formaldehyde resin, polyoxymethylene plastics, 1,4-butanediol, and methylene diphenyl diisocyanate. [40] The textile industry uses formaldehyde-based resins as finishers to make fabrics crease-resistant. [50]
Melamine-formaldehyde resins are used for plastic laminating. Urea-formaldehyde resin condensates Cured melamine resin structure Furan resin prepolymers made from furfuryl alcohol , or by modification of furfural with phenol , formaldehyde ( methanal ), urea or other extenders, are similar to amino and phenolic thermosetting resins in that cure ...
Amino-formaldehyde based resins are the best performing based on cost and ease of use. Urea melamine resins offer water resistance with more melamine offering higher resistance. It is typically used in external applications, with the coloured resin darkening the panel. To further enhance the panel properties, resorcinol resins can be mixed with ...
The formaldehyde is more tightly bound in melamine formaldehyde (MF) than it is in urea-formaldehyde (UF), reducing emissions and potential health effects. Thus LEED v2.2's EQ Credit 4.4 precludes the use of UF, but allows the use of MF. Laminated flooring is commonly used in LEED residential and commercial applications.
Duroplast, light but strong material, similar to Bakelite formerly used in the manufacture of the Trabant automobile, currently used for household objects; Urea-formaldehyde foam used in plywood, particleboard and medium-density fibreboard. Melamine resin used on worktop surfaces [18] and some plastic dishes. [19]
