杜邦公司一直积极参与、促进中国的经济社会发展。25年间，杜邦在华投资活动经历了三个阶段，即：80年代初期的设立办事处从事贸易活动，到80年代中后期开始的投资建厂、建立本地客户服务支持网络，以及本世纪初期开始的在国内兴建研发设施。杜邦公司支持中国经济和社会发展的承诺是长期的，计划到2010年，将在华投资总额增至12亿美元。为实现这一目标，公司在中国新增了许多投资项目，包括已在深圳增设多条生产线；已在常熟兴建一综合性氟产品制造基地。杜邦也已将许多的地区业务总部移至中国大陆

POM 510GR NC000杜邦--Polyformaldehyde is an important kind of thermoplastic engineering plastics. It has two kinds of polymers, homopolymer and copolymer. The main chain structure of polyformaldehyde is a high crystallinity polymer. Polyformaldehyde has high rigidity and resilience, excellent fatigue resistance and wear resistance, less creep and water absorption, good chemical corrosion resistance, solubility resistance, self-lubrication and electrical insulation. In many applications, it can replace non-ferrous metals such as steel, copper, aluminium and zinc. It is widely used in automotive industry, electronic and electrical, industrial instruments, consumer goods and other fields. In the 1960s and 1970s, the main consumption market of polyformaldehyde was in Europe and the United States. After entering the 1980s, Japan's consumption grew rapidly. In the past decade, with the gradual transfer of downstream industries of polyformaldehyde from Japan to foreign countries, Japan's consumption growth slowed down, while consumption in other parts of Asia grew fastest in the world.

The time of developing POM in China is almost the same as that of DuPont Company, which is earlier than that of Asahi Cheng Company in Japan. However, after ten years'development, there is a big gap in technology level between China and foreign companies, which is characterized by small scale, high energy consumption, low grade and unstable product In the past, POM in China missed the opportunity of industrialization of R&D achievements due to insufficient development of downstream products, small demand and planned economic system, and so on. At present, POM is only operating in pilot-scale plants, which is bound to be difficult to compete with foreign products. However, it should also be noted that POM has better conditions in terms of self-development technology level, stable operation time of 1000-ton plant and raw material sources. Some experts in the industry believe that domestic technology has the ability to build large-scale plants in some key technological links, but it needs a certain amount of capital investment. The existing production units will run well, and various auxiliary processes will be improved to prepare conditions for the expansion of the plant scale.
