POM 311DP杜邦，Nucleated Medium-high Viscosity Acetal Homopolymer       

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. Judging from the performance of two kinds of resin products, POM Its crystallinity is slightly higher and its physical and mechanical properties are slightly stronger than that of copolymerized formaldehyde, but its thermal stability and acid-alkali corrosion resistance are obviously lower than that of copolymerized formaldehyde, and its processing temperature range is narrower, while the conditions of copolymerized formaldehyde processing and shaping are not as harsh as that of homopolyformaldehyde. During the processing, less formaldehyde gas is released from thermal decomposition, which can be recycled Obviously, it affects the quality of products. These advantages are what users value and hope

POM To speed up the introduction of advanced technology from abroad, we can refer to the experience of Yuntianhua Group and consider introducing Polish technology to build a second set of devices according to the current market size and future demand growth trend, so as to improve the production capacity of POM in China, and explore the possibility of joint venture or transfer of Technology by other companies. However, in the present world, polyformaldehyde is still in the market. Under the situation of development, it is not appropriate to introduce uniform POM technology. In recent years, the flourishing downstream industry of polyformaldehyde in China has created a new opportunity for the development of POM industry in China. Whether to further develop and improve domestic technology or to introduce advanced technology from abroad, we should seize the current favorable opportunity to establish a large-scale and industrialized polyformaldehyde industry in China as soon as possible.
