What is melamine cyanurate

Melamine cyanurate is a salt synthesized from melamine and cyanuric acid. It belongs to the nitrogen series flame retardant and has two forms, namely powder and particle. When the flame retardant polyamide foam of this product is used for combustion, the carbon foam layer formed will protect the polymer and insulate it from heat and oxygen. With the addition of the product, the smoke density and toxic gas of the polymer can be greatly reduced, and the irritating hydrogen halide gas will not be generated.
