Food Grade Melamine Mold Cleaning Compound

Food Grade Melamine Formaldehyde Resin Powder with  stable-high-quality for making tableware in China.




Melamine is an organic compound with a uniform structure. Its mostly iused as a raw material for the production of melamine-formaldehyde resin (MF). The melamine resin is resistant to water, heat, arc, aging, flame retardant. With good gloss and mechanical strength, melamine formaldehyde resin is widely used in wood, plastics, coatings, paper, textile, leather, electrical and other industries.


Physical Properties: white crystalline powder, non-toxic, odorless.

Density: 1570kg/m3

Melting point: under normal pressure, 354 degrees decomposition, sublimation

Specific heat: 1.437kj/kg degrees

Solubility: soluble in glycerol

Chemical Properties: Melamine is weakly alkaline and can react with various acids to form melamine salt. In strong acid or strong alkali solution, melamine is hydrolyzed, amino group is gradually replaced by hydroxy group to form melamine diamide, melamine monoamide and cyanuric acid. Melamine reacts with an aldehyde to form an addition compound. In fact, the reaction of melamine and formaldehyde in water and liquid is the most important.

Application: It's mostly used  as a raw material for the production of melamine-formaldehyde resin (MF). The resin is resistant to water, heat, arc, aging, flame retardant, good gloss and mechanical strength, and is widely used in wood, plastics, coatings, paper, textile, leather, electrical and other industries.
