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.

Chlorinated paraffin acts as a plasticizer as well as a flame retardant. Avoids embitterment of films. It is chemically inert and non-corrosive, practically non-volatile, non-flammable and imparts flame-resistant properties. Shows excellent resistance to water and decomposes before boiling. It is insoluble in water and glycerine, soluble in many organic solvents, slightly soluble in aromatic hydrocarbons, aliphatic hydrocarbons, ketones, esters, vegetable and animal oils and miscible with benzene, chloroform, ether, carbon tetrachloride. With viscosity ranging from 10-20 poises, it is also used in the preparation of mastics and emulsion paints.
