MELAMINE (108-78-1)

Product Overview

Melamine is an organic compound with the formula C₃H₆N₆. Melamine-formaldehyde resin (MFR) is a crucial component in strong plasters, used in dental casts and textile finishes, with reported cases of sensitization. It is a white solid organic compound, and its production involves the urea process, utilizing ammonia on urea. Melamine, the base compound, forms a six-membered heterocyclic ring with alternating carbon and nitrogen atoms and three amino groups. Condensation polymerization with methanal produces melamine resins, essential in thermosetting plastics.

Melamine is an organic compound with the chemical formula C₃H₆N₆. It is a white solid that forms a trimer of cyanamide, featuring a 1,3,5-triazine skeleton.

Melamine is a trimer of cyanamide, and its structure includes a 1,3,5-triazine skeleton. This structural arrangement contributes to its unique properties and applications in various industries.

Melamine contains 67% nitrogen by mass, similar to cyanamide. Its derivatives exhibit fire-retardant properties, releasing nitrogen gas when burned or charred. This characteristic contributes to the material’s fire-resistant nature.

Melamine is widely used in the production of melamine-formaldehyde resins, which have applications in the manufacturing of laminates, coatings, and molded products. Additionally, melamine foam is employed as a soundproofing and insulating material.

While melamine itself is generally considered safe, it’s essential to adhere to proper handling procedures, especially when dealing with its derivatives. Safety measures should be followed to prevent exposure to potentially harmful substances.
