Égésgátlók

Égésgátlók, also known as flame retardants, are chemical additives that are incorporated into materials to inhibit, suppress, or delay the production of flames. Their primary function is to reduce the flammability of a wide range of products, thereby increasing fire safety. These substances work through various mechanisms, including interfering with the chemical reactions of combustion, forming a protective char layer on the material's surface, or releasing water to cool the burning material and dilute flammable gases.

The application of égésgátlók is extensive, found in plastics, textiles, foams, coatings, and electronics. They are crucial in improving the fire performance of materials used in construction, transportation, furniture, and consumer goods. Different types of égésgátlók exist, including halogenated compounds, phosphorus-based compounds, and inorganic compounds like aluminum hydroxide and magnesium hydroxide. Each type has specific properties and is suited for different applications and material types.

While égésgátlók significantly contribute to fire safety, their use has also raised environmental and health concerns. Some traditional égésgátlók, particularly certain halogenated types, have been found to persist in the environment, bioaccumulate in living organisms, and pose potential health risks. This has led to increased research and development of more environmentally friendly and less toxic alternatives, often referred to as "green" égésgátlók. Regulatory bodies worldwide continue to evaluate and restrict the use of certain égésgátlók based on their risk assessments, driving innovation towards safer fire-retardant solutions.
