PTFE is widely used and China’s production capacity is highly concentrated

Polytetrafluoroethylene (PTFE) is a white, odorless, non-toxic polymer, commonly known as the “King of Plastics”. It is polymerized from the monomer tetrafluoroethylene. It is almost insoluble in all solvents and has high temperature resistance, cold resistance, It has excellent properties such as corrosion resistance, acid/alkali resistance, good dielectric properties, extremely low friction coefficient, and self-lubrication. It is widely used in national defense, electrical, chemical, aerospace, instrumentation, construction, atomic energy, machinery, textiles, food, and medicine. , metallurgy and many other fields.

PTFE can be divided into two categories: dispersed PTFE and suspended PTFE. Dispersed PTFE is available in powder form and concentrated dispersion. The powder form is mainly used to process pipes, raw material belts, microporous films, fibers, thin-walled tubes, etc. The concentrated dispersion is mainly used in various coatings.

According to the“2023-2028 Polytetrafluoroethylene Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center , In recent years, my country’s polytetrafluoroethylene production capacity has continued to expand, and the industry has developed rapidly. my country’s polytetrafluoroethylene production capacity was 118,000 tons in 2016 and 189,000 tons in 2022, with a compound annual growth rate of 8.2% during the period. Among them, my country’s polytetrafluoroethylene production capacity will account for 60.9% of the world’s total production capacity in 2022. There are only a small number of domestic polytetrafluoroethylene manufacturers, and their production capacity is highly concentrated. Shandong Dongyue, Haohua Technology, Juhua Co., Ltd., Daikin, Sanaifu, Jiangsu Meilan, Jiangxi Liwen, and Fujian Sannong are the major polytetrafluoroethylene manufacturers in my country. Major manufacturers of tetrafluoroethylene. Among them, three companies, Shandong Dongyue, Haohua Technology and Juhua, account for about 65% of my country’s total PTFE production capacity.

PTFE is powerful and widely used. In terms of engineering plastics, PTFE can be made into PTFE tubes, films, and strips, which can be used in pump valves, radio equipment, radar, high-frequency communication equipment, and corrosion-resistant pipelines; in medical terms, PTFE biodegradable It has good capacitance, non-toxic, non-allergenic and strong inertness, and can be made into important biological functional materials such as artificial blood vessels and heart valves. In terms of environmental protection, compared with traditional filter materials, bag dust collectors made of polytetrafluoroethylene are more stable Better, with smaller and more uniform pore sizes, higher filtration efficiency, and lower operating friction, it can be used for PM20.5 filtration and flue gas dust removal in cement plants, power plants, carbon black plants and other factories; in terms of kitchenware, PTFE is resistant to High temperature, self-lubricating, can be used as lining for non-stick pans and other kitchen utensils.

From the perspective of the demand structure of the downstream application market, chemical industry, electronics, automobile and transportation, kitchenware, medical health, and construction industry are the main application areas of PTFE. Among them, the chemical industry accounted for 44.7% of the total downstream demand for PTFE, ranking first; the electronics field accounted for 17.0%, ranking second; automobile and transportation accounted for 11.1%, ranking third.

Industrial analysts said that polytetrafluoroethylene with excellent performance is an ideal material for making high-frequency substrates and is widely used in artificial intelligence , military electronics, 5G communications and other high-end fields, but such products are currently monopolized by developed countries such as Europe and the United States. my country’s PTFE applications are mainly concentrated in low-end products such as pipes, strips, sheets, films, kitchenware coatings, and sealing tapes. In order to expand my country’s PTFE market space, representative companies such as Xinzhoubang, Walter Co., Ltd., and Dongyue Group have begun to deploy high-end markets, which is expected to promote the further development of my country’s PTFE industry.
