flammemodstand

Flammemodstand, also known as flame retardant, is a substance or treatment applied to materials to reduce their flammability. It is widely used in various industries, including construction, automotive, and electronics, to enhance safety by preventing or slowing down the spread of fire. Flame retardants can be classified into several categories based on their chemical composition and mechanism of action. These include halogenated compounds, phosphorus-based compounds, and intumescent systems. Halogenated compounds, such as bromine and chlorine, release halogens when heated, which inhibit the combustion process. Phosphorus-based compounds form a protective char layer on the material's surface, preventing oxygen from reaching the burning material. Intumescent systems expand and form a protective char layer when exposed to heat, creating a barrier that slows down the spread of fire. The effectiveness of flame retardants can be evaluated through various tests, such as the Limiting Oxygen Index (LOI) and the UL-94 test. However, the use of flame retardants has raised environmental and health concerns due to the potential release of harmful substances during combustion. As a result, there is ongoing research to develop more environmentally friendly and safer flame retardant alternatives.
