Development Status of Ammonium Polyphosphate and Phosphorus Flame Retardant in the World

Date:2016年10月20日 09:21

In recent years, the development of halogen-based flame retardants has been greatly affected by the influence of decabromodiphenyl ether and hexabromocyclododecane on the inclusion of persistent organic pollutants, resulting in halogen-free flame retardants Agent concept. In contrast to halogen flame retardants, this concept has led to the development of research and manufacturing of halogen-free flame retardants, including phosphorus-based flame retardants. And after 2005, bromine prices continued to rise, and domestic phosphorus prices in sharp contrast to the price, making the price gap between the two quickly increased, and even the price of brominated flame retardants was once higher than the majority of phosphorus More than double the price of flame retardants. As a result, the rise in the price of brominated flame retardants has driven the rapid growth of phosphorus or phosphorus-based flame retardants in the period from 2005 to 2012.

China's flame retardant consumption in 2012 is about 474,000 tons, of which the largest proportion of phosphorus-based flame retardants, the total amount of about 17.9 million tons, compared to 2008 90,000 tons of consumption, the growth rate of 16.4%. Phosphorus flame retardant market to maintain high growth for many reasons, we believe that the most important reason is its main rival bromine flame retardants caused by high prices, followed by the downstream market driven, 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. The global BR-based flame retardant giants are concentrated in Albemarle, Keda and ICL three, since 2010, the three companies continue to improve their own flame retardant and bromine-related products prices. As the bromine flame retardant prices continue to rise, will inevitably stimulate the consumption of phosphorus-containing flame retardants to promote the growth of phosphorus-containing flame retardant consumer market.

Second, the rapid development of downstream industries led to the growth of phosphorus-containing flame retardants. China phosphorus-containing flame retardant halogenated phosphate and halogen-free phosphate consumption accounted for 74% of phosphorus-containing flame retardant consumption, mainly for building insulation materials, fire retardant coatings, adhesives and CCL, composite materials Development of faster areas, including a large number of halogen-free phosphate for PC / ABS alloy; ammonium polyphosphate is mainly used for fire coatings and general plastics; hypophosphite is mainly used in engineering plastics polyamide, polyester and other engineering plastics; Phosphorus flame retardant is mainly used for engineering plastics and general plastic flame retardant; phosphorus mafic flame retardant is mainly used for CCL.

China since the 1980s began to study the synthesis and application of ammonium polyphosphate, in recent years the development is particularly rapid, in 2003 the amount of domestic ammonium polyphosphate reached 0.8 million tons, and in 2012 reached 26,000 tons, showing continued growth trend. With the country's efforts to strengthen the technical requirements of flame retardant, in the future development of phosphorus-based flame retardant with its price advantage will continue to play a steady development role.
