Octabromoether, endowing flammable polymers with flame retardancy
In the 1950s, with the "instantaneous explosion" of material science and technology, organic polymer materials began to be widely used in various fields of production and life. Nowadays, plastics, rubber and textiles, which are the main components of macromolecule materials, are indispensable production elements. Electrical appliances and tableware made of macromolecule materials bring great convenience to our life, but also bring us many potential safety hazards. Octabromoether is needed at this time. It's time!
Because the oxygen index of polymer materials is generally low, air containing 21% oxygen can meet the combustion conditions of most polymer materials. In addition, the smoke and poisonous gases emitted by polymer materials when burning can also pollute the environment by colleagues who endanger human health. In order to reduce the flammability of polymer materials and avoid fire, octabromoether flame retardants began to emerge. Flame retardants, as the name implies, prevent materials from being flammable.
There are many kinds of flame retardants. Generally speaking, we can divide them into organic flame retardants and inorganic flame retardants. Organic flame retardants include octabromoether, tetrabromoether and so on.
The main component of octabromoether is halogen organic matter. Free radicals produced by polymer degradation at high temperature are the conditions to maintain the combustion of organic matter. Hydrogen halide gas produced by halogen flame retardants during thermal decomposition can capture free radicals and then achieve the purpose of organizing flame diffusion.
Hydrogen halide itself can not be burned, and its density is higher than that of air. Octabromoether will form a layer of gas barrier on the surface of polymer materials, thus blocking the contact between polymer materials and oxygen.
