teflon yes The product of the development of chemical industry to a higher level. With the development of various new application scenarios, Polytetrafluoroethylene (PTFE) It has become a fluoropolymer with large production and fast consumption growth. Over the years of development, the global PTFE industry has experienced several mergers and reorganization. At present, the competition pattern of the industry is stable. Overseas production capacity is concentrated in DuPont. In the past two decades, with the breakthrough of domestic fluorine chemical technology, the abundant fluorite resources and the advantages of the terminal market, the production capacity of PTFE has gradually shifted from overseas to China. In 2019, the domestic PTFE production capacity will be about 140000 tons, accounting for more than 40% of the global total capacity. However, from the perspective of production capacity structure, domestic production capacity is still dominated by injection grade low-end products, while domestic consumption growth is slow. The capacity utilization rate of the industry has been kept at a low level of less than 70%. In addition, high-end modified PTFE products mainly rely on imports.

At present, the domestic PTFE industry is relatively loose. Judging from the price difference between PTFE dispersion resin and raw material R22, it is close to the historical bottom at the beginning of 2015. However, from the perspective of the supplier, R22 and hydrofluoric acid equipment should be equipped upstream for PTFE production. In addition, PTFE equipment also has the problem of by-products from waste acid treatment. Therefore, environmental factors limit the actual starting level and supply elasticity of the industry. From the perspective of demand, the obstacles that previously restricted the development of China's materials industry were: the application scenarios were mainly in developed countries. As China has reached the world's advanced level in the field of 5G and lithium batteries, Chinese companies have also expanded the market space for the development and application of advanced materials. Later, the demand for PTFE will appear in high-frequency copper clad laminates, R radio frequency cables and base stations for 5G communication, and the field of antenna filters ushered in substantial growth. The launch of Tesla's ultra-high nickel cathode material based on dry electrode technology (i.e. lithium battery technology) will not only drive the technological transformation of the lithium battery industry, but also increase the huge demand for PTFE adhesives.
