Palonsuojakkeet, often translated as fire retardants, are chemical additives incorporated into materials to inhibit, suppress, or delay the production of flames. They are crucial in enhancing the fire safety of a wide range of products, from textiles and plastics to building materials and electronics. The primary function of a fire retardant is to interfere with the combustion process, which typically involves a chain reaction of exothermic chemical reactions.

There are several mechanisms by which fire retardants operate. Some work by releasing water vapor when heated, which dilutes the flammable gases and cools the material. Others form a protective char layer on the surface of the material, acting as a barrier to prevent heat and oxygen from reaching the underlying combustible substance. Still others interfere with the radical chain reactions in the gas phase that sustain the flame.

The types of fire retardants used vary depending on the material they are intended to protect and the specific fire safety standards required. Common examples include halogenated compounds, phosphorus-based compounds, nitrogen-based compounds, and inorganic fillers like aluminum hydroxide and magnesium hydroxide. Environmental and health concerns have led to a continuous effort to develop and implement more sustainable and less toxic fire retardant solutions. Regulatory bodies worldwide set standards and guidelines for the use of fire retardants to ensure product safety and minimize potential risks.
