Melamine powder 99.8%


1.Physical properties:
White crystalline powder, innoxious, flavorless.
Relative density: 1570kg/m³
Melting point: It can be decomposed in 354¡æ under ordinary pressure.
Sublimation temperature: 300¡æ
Dissolvability: It can be dissolved in carbinol, formaldehyde, acetic acid, hot glycol, glycerin, pyridine; it is slightly dissolved in water, ethanol; it can't be dissolved in aether, benzene, and carbon tetrachloride. Its water solution presents alkalescence.

2.Chemical properties:
Melamine powder 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.
