With people's emphasis on the flame retardancy of combustible materials, flame retardants have been greatly developed with the widespread application of polymer materials, and with the increase of people's awareness of environmental protection, new types of flame retardants continue to appear, and some emerging technologies It has also been continuously applied to the research and production of flame retardants. In summary, the development of Shanghai flame retardants in the future will generally have the following trends:

(1) Develop synergistic flame retardants such as phosphorus, nitrogen, and bromine in molecules or intermolecular combinations.

(2) The development of high-efficiency, non-toxic flame retardants with little effect on material properties, which leads to the development of reactive flame retardants and the development of additives with good compatibility.

(3) Development of a series of flame retardants with different applications. At present, foreign countries are mainly focusing on miniaturization, surface modification, microencapsulation, and synergy synergy.
