Product Details
Commonly known as "protein essence" or "mi'an" in Chinese nomenclature, melamine is a nitrogen-rich triazine heterocyclic organic compound designed exclusively for industrial chemical applications. It presents as odorless, white monoclinic crystals, with a water solubility of only 3.1 g/L at room temperature. While barely dissolving in water, it shows excellent solubility in formaldehyde, acetic acid, hot ethylene glycol, glycerol and pyridine.
The compound remains completely insoluble in acetone and ether. It carries clear health hazards and is strictly prohibited from being used in any food processing or as a food additive. However, some unethical producers once adulterated dairy products with melamine, in a deliberate attempt to artificially boost nitrogen readings and falsify protein content test results.

Production Application
Primary feedstock for melamine-formaldehyde (MF) resins, widely used in decorative laminates, wood adhesives, amino plastics and surface coatings.
Halogen-free flame retardant component for paints, plastics, paper making and textile processing.
Functional additive for cement water reducers, paper reinforcing agents and textile anti-crease finishing agents.
Crosslinking curing agent for amino-resin coil and can coatings, to enhance hardness, chemical and stain resistance.
