POM has a limit oxygen index of only 15%, which is a very flammable plastic variety. As engineering plastics, POM is widely used in automobile, electronics, electrical and building materials, which require high flame retardancy of materials. Due to the poor compatibility of POM with other materials, it is difficult to prepare flame retardant POM with excellent properties by adding flame retardant directly. Asahikawa Industrial Co., Ltd. of Japan has applied for a patent for a flame retardant polyformaldehyde super-extender. The flame retardant polyformaldehyde superelongation is prepared by coating vinylidene chloride polymer latex on the superelongated polyformaldehyde or by mixing the latex with metal oxides or hydroxides. Each gram of polyformaldehyde was coated with 0.2-0.5g, and a continuous film was obtained. The oxygen index was more than 40, and the flow temperature was more than 100 C.

From the production process of POM, formaldehyde is used as the polymerization monomer in homopolymerization. Its chemical properties are very active, which brings many problems to the refining and polymerization process. The copolymerization method uses triformaldehyde as the polymeric monomer. Triformaldehyde is a stable six-segment ring. Compared with formaldehyde, it is more convenient to purify and polymerize. So when the process route of triformaldehyde appears, industry seldom considers formaldehyde as the polymeric monomer. At present, the copolymerization technology of triformaldehyde as the polymeric monomer accounts for about the total of polyformaldehyde in the world. Production capacity.
