Copolymerized formaldehyde
Thread Content
DuPont in the United States and Asahi Kasei in Japan, which possess homopolymerization technology, each hold a 50% stake in a facility in Zhangjiagang for producing 60,000 tons of POM; one of the production lines with a capacity of 20,000 tons has been in operation for many years. Has it been expanded to 60,000 tons now?
I would like to ask the experts: What is the current total production volume of polyoxymethylene in China? Is there any margin left?
Production has stopped everywhere; with Tianji and Yongmei starting up next year, where will there still be any surplus?
There is still headroom; attention should be paid to market expansion. :handshake :handshake
Let the OP’s friend discuss in more detail how the market should be expanded: victory:
At present, the market for polyoxymethylene is indeed in a poor state due to the financial crisis; most domestic polyoxymethylene manufacturers have stopped production for maintenance. As more domestic plants for producing polyoxymethylene come online, price wars will be inevitable. A potential market for this material lies in its use as a substitute for other plastics in a wider range of applications. In the competition of the chemical industry market, countless experiences have shown us that whether there is a surplus is not determined by any expert’s predictions, but rather by the market itself and its expansion.
Please pay close attention to the development of China’s automotive industry. The use of polyoxymethylene in the domestic automotive sector began in 2007, whereas its use abroad is already quite mature. China’s massive automobile market will strongly drive up the demand for polyoxymethylene. As far as I know, domestic automakers such as FAW and SAIC are already using polyoxymethylene in their high-end vehicles; it was too expensive to use in the past, but this demand is firm! :lol :lol :lol :lol
Well analyzed: handshake :handshake
Depending on the production process, polyoxymethylene can be produced through homopolymerization or copolymerization methods, with the latter being more common. The production capacity of copolymerized POM accounts for about 80% of the total polyoxymethylene production capacity, and copolymerized POM technology is set to be the direction of development in the future.

(1) Homopolymeric formaldehyde production process: Industrial formalin solution is first converted into polyformaldehyde or 5-formaldehyde with a lower molecular weight; thereafter, it is cracked and purified to obtain high-purity formaldehyde gas. This gas is then catalytically polymerized in an inert solvent, and after end-group modification, drying, and granulation, homopolymeric formaldehyde product is obtained. The production process of homopolymerized formaldehyde is represented by DuPont Company. (2) Production process of copolyoxymethylene: Using polyoxymethylene as the raw material and dioxolane as the comonomer, the product is obtained through solution polymerization or bulk polymerization in the presence of a boron trifluoride ether (or butyl ether) complex catalyst.
