Melamine
Melamine
Melamine (chemical formula: C3N3 (NH2) 3), commonly is known as melamine, protein concentrate, is a triazine containing nitrogen heterocyclic organic compounds, used as chemical raw materials. Industrial melamine is made from urea, and the product quality conforms to GB/T9567-2016.
Melamine is a basic intermediate product in organic chemistry and has a wide range of USES. It is mainly used as raw materials for the production of melamine/formaldehyde resin (MF), melamine glue for building formwork, impregnated paper and melamine tableware.
Melamine can also be used as a flame retardant, water reducer, formaldehyde cleaner, etc. The resin hardness is higher than urea-formaldehyde resin, non-flammable, water resistance, heat resistance, aging resistance, arc resistance, chemical resistance, good insulation performance, gloss and mechanical strength, widely used in wood, plastic, paint, paper, textile, leather, electrical, medical and other industries.
