 Physical and Chemical Characteristics:

Physical properties:
Appearance: White, innoxious, flavorless crystalline powder.
Solubility: Soluble in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerol, pyridine; Slightly

soluble in water, ethanol; Do not dissolve in ether, benzene and carbon tetrachloride. Weakly alkaline aqueous solution.

Chemical properties:
Melamine presents alkalescence, can react with various acidums to generate melamine salt. In strong acid or strong

alkali liquor, melamine will hydrolyze amido group will be slowly replaced by hydroxyl, thus generate

ammeline, Cyanuric Acid and Ammelide. It can react with aldehydes to produce addition compounds.

Among them, the reaction of melamine and formalin is the most important part.

~Application:

1.  Resin raw materials: in the production of melamine-formaldehyde resin.

2.  Decorative veneers:Melamine can be used as veneer of plane, ship and furniture, also as fire, earthquake, and heat

     resistant housing decorative material.

3.  Coating: Cross-linking agent used in coating of acrylic acid series, alkyd series and epoxy series.

4.  Molding powder: It can be made into high-class insulating material used in daily vessels, sanitary ware,

imitation porcelain tableware, and electrical equipment.

5.  Paper treating agent: It can be used as paper treating agent after the etherification by diethyl ether and produce anti-wrinkle,anti-shrink, and moisture proof bank note and high-rank paper of military map etc.

Packing:
