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 of China Melamine 99.8% Powder:
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.
