World development direction of flame retardant for plastics

More and more widely used in plastics production and all areas of life, but at the same time, because of the flammability of plastic bow} also brought fire from human casualties and economic losses. Therefore, from the 1960s onwards, some developed countries began production and application of flame retardant plastic. The 1970s, consumption and foreign varieties of flame retardants rapid growth, annual growth rate of 6 to 8 percent. Currently, the consumption of flame retardants has leapt to second place plastic additives, plasticizers, second only to the great variety.PVC plasticizer
Of blocking fuel science research started late, in 1985 the country only 40 kinds of varieties of flame retardants. Production of about 5,000 tons, the annual output of only a tenth of the U.S. gas flame, but by 1998, the domestic flame over 70,000 tons of annual output has reached 200. Annual demand of more than 90,000 tons.
Our chlorine-based flame retardants, 69% of the inorganic flame retardant system accounted for only about 17%, half of which is antimony dioxide, and aluminum hydroxide, magnesium hydroxide is less than 10%, accounting for halogen 80% of the entire flame retardants, and the current system of foreign inorganic flame retardants, accounting for 50% of a total of 60%, the main varieties are aluminum hydroxide and magnesium hydroxide.PVC impact modifier
Our flame of a late start, though already achieved development, but compared with the advanced countries, in both yield and product structure there is a gap. At present, the domestic research and development of new port focused on inorganic flame retardants, red phosphorus microencapsulation, intumescent flame retardants and other fields, and achieved certain results. Halogen-free, efficient, low smoke, low toxicity of new flame retardants in today's development direction.
