Product Introduction
Melamine is a white, crystalline powder with no odor. It features a triazine - based heterocyclic structure, giving it stability under normal conditions. However, high - temperature decomposition releases toxic cyanide - related byproducts.
It has low water solubility (sparingly dissolves in water) but mixes with solvents like methanol or formaldehyde. Legally, it's strictly regulated in food - contact contexts due to health risks-especially its link to kidney damage when illicitly added to food to falsify protein tests.

Product Application
Melamine's value lies in industrial applications (never for food/feed). Key uses include:
a) Resins & Plastics
- Melamine - Formaldehyde (MF) Resin:
Reacts with formaldehyde to form a hard, heat - resistant resin. Used for:
- Tableware: Durable "melamine" dishes (e.g., camping plates) that resist chipping.
- Laminates: Decorative surfaces for furniture/cabinets (scratch - resistant, easy to clean).
- Electrical Components: Insulators in sockets/switches (good electrical - heat stability).
b) Adhesives & Coatings
- Woodworking Adhesives:
Bonds wood fibers in plywood/particleboard, boosting strength and moisture resistance.
- Industrial Coatings:
Added to paints for metal/equipment, enhancing hardness, chemical resistance (e.g., factory floors, vehicle parts).
c) Flame Retardants
High nitrogen content makes it a flame - suppressing additive. Mixed into:
- Plastics (e.g., electronics casings)
- Textiles (e.g., upholstery for fire - safe furniture)
- Building materials (e.g., insulation foams)
d) Paper & Textile Additives
- Paper Industry: Strengthens paper (e.g., packaging for heavy items, improving tear resistance).
- Textiles: Enhances fabric properties (e.g., wrinkle resistance in clothing, flame - retardant finishes for curtains).
