Some flame retardants work under the concept of thermal shielding. In this process, a thermal barrier is formed between the burning part of material and the unaffected part. The thermal barrier insulated the unburned material from the flames. Intumescents are classic examples of the type of chemical that achieves thermal shielding. [...]

One type of flame retardant is a chemical that degrades endothermically. Examples of these types of chemicals are magnesium hydroxide, aluminum hydroxide and many different hydrates. An endothermic reaction is one where heat is absorbed. Systems in which an endothermic reaction is taking actually undergo a relative decrease in temperature. Hence, [...]
