Product Usage
Melamine is widely used in the production of high-pressure laminating resins, such as decorative countertops, molded compounds like dinnerware, and surface coating resins for appliances and automotive topcoats. It is also utilized in textile and paper treatment resins. Other applications include adhesive resins for bonding lumber, plywood, and flooring, as well as resins used in leather tanning. Melamine, melamine cyanurate, other melamine salts, and guanidine compounds are among the most commonly used nitrogen-containing flame retardants. Specifically, melamine serves as a flame retardant additive for polypropylene and polyethylene, while melamine cyanurate is commercially applied as a flame retardant for polyamides and terephthalates.
