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 ]
Urea-formaldehyde resin condensates Cured melamine resin structure. Furan resin prepolymers made from furfuryl alcohol, or by modification of furfural with phenol, formaldehyde , urea or other extenders, are similar to amino and phenolic thermosetting resins in that cure involves polycondensation and release of water as well as heat. While they ...
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 ...
Chemicals typically used for this purpose include epichlorohydrin, melamine, urea formaldehyde and polyimines. These substances polymerize in the paper and result in the construction of a strengthening network. Cationic starch. To enhance the paper's strength, cationic starch is added to wet pulp in the manufacturing process. Starch has a ...
Formaldehyde resins are synthetic resins based on formaldehyde together with a co-mononer, such as: Melamine formaldehyde (MF) Urea-formaldehyde (UF) Phenol ...
In situ polymerization of such formaldehyde systems usually involves the emulsification of an oil-phase in water. Then, water-soluble urea/melamine formaldehyde resin monomers are added, which are allowed to disperse. The initiation step occurs when acid is added to lower the pH of the mixture.
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.
Particleboard with veneer. Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde-based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.
