Introduction

Nitrogen-based flame retardants are all based on the carbon – nitrogen – hydrogen compound melamine C₃H6N6. This is the same molecule as that which, combined as a resin, is widely used to make kitchen surfaces and utensils.

Nitrogen flame retardants include melamine itself or homologues, and compounds derived from melamine by combination with organic or inorganic acids (with boron, nitrogen, phosphorus …). They are used in foams, intumescent coatings and various polymers, in particular nylons.
