In recent years, the development of halogen-based flame retardants has been greatly affected by the inclusion of deca-BDE and HBCD as persistent organic pollutants, and as a result, halogen-free flame retardants The concept of agent. Corresponding to halogen flame retardants, this concept has led to the development of research and manufacture of numerous halogen-free flame retardants including phosphorus flame retardants. However, after 2005, the price of bromine continued to rise, in sharp contrast with the price stability of domestic phosphorus resources, resulting in a rapid increase in the price gap between the two. Even the price of brominated flame retardants once surpassed that of most phosphorus Department of flame retardant prices more than doubled. Therefore, the price of brominated flame retardants promoted the phosphorus-based or phosphorus nitrogen-based flame retardants in the rapid growth of the market between 2005 and 12 years.

In the past 16 years, the consumption of flame retardants in China was 474,000 tons, of which the largest proportion of phosphorus flame retardants was about 179,000 tons, an increase of 16.4% over the figure of 90,000 tons in 12 years. There are many reasons for the rapid growth of the market for phosphorus-containing flame retardants. In our opinion, the most important reason is that the price of brominated flame retardants, which is the main competitor, has risen sharply, followed by the downstream market. The third is the impact of policies and regulations.

First, the price of brominated flame retardants led to the rapid growth of phosphorus-containing flame retardants. Global brominated flame retardants giant concentrated in Albemarle, Branch Poly Asia and ICL who, since 10 years, the three companies continue to improve their own flame retardants and bromine-related products prices. As the price of brominated flame retardants continues to rise, inevitably stimulate the consumption of phosphorus-containing flame retardants and promote the growth of phosphorus-containing flame retardants in the consumer market.

Second, the rapid development of downstream industries led to the consumption of phosphorus-containing flame retardants. The proportion of phosphoric acid esters and halogen-free phosphoric acid esters in China's phosphorus-containing flame retardants accounted for 74% of the consumption of phosphorous-containing flame retardants, which are mainly used in building insulation materials, fire retardant coatings, adhesives and copper clad laminates, composites, etc. The rapid development of areas, including a large number of halogen-free phosphate ester for PC / ABS alloy; ammonium polyphosphate is mainly used for fire-resistant coatings and general plastics; hypophosphite is mainly used in engineering plastics, polyamides, polyester and other engineering plastics; Phosphorus flame retardants are mainly used in engineering plastics and general plastics flame retardant; Phosphazene flame retardants are mainly used in CCL.

According to the investigation of the fire retardant industry survey report, China started to study the synthesis and application of ammonium polyphosphate in the 1980s. In recent years, the development has been particularly rapid. In 2003, the domestic use of ammonium polyphosphate reached 0.8 million tons and reached 2.6 in 2016 Tons of tons, showing a continuous growth trend. With the strengthening of national fire retardant technology requirements, in the future development, phosphorus flame retardants will continue to play a steady role in the development of their price advantage.

Flame retardant industry is increasingly developing into a global industry, on the one hand performance in many flame retardant companies are involved in world trade, the competition in the industry has not only limited to a country or region within the competition, But competition among players in the global marketplace; on the other hand, flammable regulations that appear in one country or region tend to have an impact on global industry rules. End-product manufacturers such as consumer electronics are not required to fire retardant products in countries and regions where they are registered, but their products must pass the fire-retardant standards of the country of sale or the country of import if their products are sold in international markets . Therefore, export-oriented product manufacturers, in order to make their products can be sold to as many countries and regions, generally tend to adopt the most stringent standard flame retardant formulations, which led to the global fire retardant products throughout Industrial chain development.
