The biggest use of bromine is as a flame retardant. In addition, it is also used in mercury removal and air purification.With the wide application of polymer materials such as plastics (7910, 5.00, 0.06%) in home environment, public places and vehicles, flame retardants are becoming more and more necessary fire retardant additives.

  Currently, flame retardants are mainly used in four areas: transportation, electronic and electrical equipment, furniture, and buildings and building materials.There are more than 200 products in the flame retardant family, which can be divided into bromine, phosphorus, nitrogen, silicon and inorganic flame retardants according to different elements.This diversity is also necessary because the materials and products that are intended to have fire resistance vary greatly in their properties, composition and even application.Certain flame retardants may be well suited for certain uses, but not for others.In other words, no single flame retardant is a panacea, and different solutions must be selected for different applications.Material engineers will choose appropriate flame retardants according to the structure and performance of the material, such as 80% to 90% of printed circuit boards are bromine flame retardants.

  Brominated flame retardants are very efficient and can capture free radicals in the combustion chain reaction, stop or slow down the chain reaction, so as to play the role of flame retardant.In addition, bromine flame retardants are in the forefront of all kinds of existing flame retardants, and have little influence on the performance of the substrate. They are suitable for flame retardant of various plastics, rubber (10780, -50.00, -0.46%), fiber and coating.

  The production and application of flame retardants have entered a stage of steady development after vigorous development in the early 1980s.With the development and continuous expansion of China's synthetic materials industry, flame retardants have broad market prospects in chemical building materials, electronics and electrical appliances, transportation, aerospace, daily furniture, interior decoration, clothing, food, housing and transportation, etc. [1].In addition, coal field, oil field, forest fire extinguishing and other fields have also promoted the rapid development of flame retardant and fire extinguishing agent production in China.In China, flame retardants have become the second largest additive of polymer material modification after plasticizer.In recent years, the production and consumption of flame retardants in China continue to develop, the consumption of flame retardants in China has risen sharply, and the increased market share mainly comes from two aspects: electronic appliances and automobile market.
