Product description: Melamine
Molecular formula: C3N6H C3N3(NH2)3
CAS RN: 108-78-1;94977-27-2
EC NO : 203-615-4
Molecular weight:126.12
Properties:
Physical properties: White crystalline powder, innoxious, flavorless.
Relative density: 1570kg/m3
Melting point: It can be decomposed in 354 under ordinary pressure.
Sublimation temperature: 300¡
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.
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.

Uses: Melamine is a semi-finished product in organic chemical industry with even structure and vast applications; it is mainly used as the material to produce melamine formaldehyde (MF) colophony. Owning the abilities of fire-resistant, water-resistant, hot-resistant, age-preventing, electric arc resistant, bearing chemical corruption, perfect insulation capability, gloss grade, and machinery intention, and good thermal-setting capacity, it is widely used in wood, plastic, dope, paper-making, textile industry, leather, electric, and medicine, etc.
The actual applications are:
1, decorative veneer plywood.
2, coating
3, moulding powder
4, paper
5, Mixed with other materials, melamine formaldehyde (MF) resin also can be used to produce fabric finished agent, tannage agent of leather, glazing agent, waterproof agent, rubber adhesive, high efficient water reducing agent of cement (naphthalene as material), and nitridizing agent of steel.
Packing: 25/50KG plastic bag lined woven bag or following your demand.
Storage: Kept in shady and ventilative places. Don't be stored or transported together with acid or oxidizer
