Finding a balance between fire protection and environmental protection is really not an easy task. After the promulgation of a series of environmental protection policies, many traditional flame retardants have been restricted to varying degrees. So how do we determine whether it is an environmentally friendly flame retardant? What is the connection between fire protection and environmental protection? Today I will share with you.

Current flame retardants can be broadly divided into organic and inorganic, halogenated and halogen-free categories. Among them, the representatives of organic flame retardants are some compounds with bromine, nitrogen and red phosphorus; the representatives of inorganic flame retardants are antimony trioxide, aluminum hydroxide, magnesium hydroxide and silicon flame retardant materials . Generally speaking, everything has its advantages and disadvantages. Organic flame retardants have good affinity, but there has been controversy on environmental protection. Halogen-free flame retardant can be called a very environmentally friendly flame retardant, which not only has the advantages of low addition, high flame retardant efficiency and wide use, but also meets the requirements of low smoke, nontoxic and environmental protection. However, the component, red phosphorus, is extremely susceptible to oxidation and moisture absorption in the air, which can seriously cause dust explosion. Its scope of application is limited by inconvenience in transportation and poor material compatibility. In order to make up for this deficiency, we have expanded the scope of application of red phosphorus and processed it into microencapsulated red phosphorus by adopting foreign advanced microcapsule coating technology. Not only has overcome the disadvantages of red phosphorus before, its dispersibility, physical, mechanical properties, thermal stability and flame retardancy have been greatly improved and improved.
