The supply and demand status of China's PTFE industry in 2019, and the industry has a wide range of applications
At present, the industrialized fluoropolymers mainly include PTFE (polytetrafluoroethylene), FEP (perfluoroethylene propylene copolymer), PVDF (polyvinylidene fluoride), PVF (polyvinyl fluoride) and FKM (fluoro rubber) Wait. The PTFE series is the most important fluoropolymer, and its production and sales account for more than half of all fluoropolymers.
PTFE products are an important class of polymer products, and their applications involve many fields of military industry and civilian use, and have good development prospects. At present, my country has basically occupied the market in low-end products such as PTFE sheets, pipes, gaskets and sealing tapes, but there is still a big gap between high-end products and western developed countries, such as e-PTFE artificial blood vessels and medical sewing. There are no industrialized products in my country, such as thread and heart patch, and the products used are mainly imported, which are expensive. Therefore, further research on the relationship between the structure and performance of PTFE products, optimizing product processing technology, developing high-end products with excellent performance, and exploring new applications are still the direction of future efforts.
At present, the synthesis process of foreign PTFE resin has reached a relatively high level, but there is still a big gap in the domestic high-end resin field, resulting in the domestic production of high-performance PTFE materials, which can only be imported from foreign PTFE resins at high prices. Especially in the production of unconventional materials for military industry, aerospace and medical applications. Therefore, it is recommended that the government encourage domestic polytetrafluoroethylene resin synthesis enterprises to develop high-performance polytetrafluoroethylene resin in the form of policy preference or special policy funding to solve the current domestic problem of stuck necks and meet high-end fields such as military industry, environmental protection and medical care demand.
At present, my country has become a major producer and supplier of PTFE in the world. Since 2010, it has maintained an export volume of about 20,000 tons/year. In 2019, my country exported 21,000 tons of PTFE, accounting for 25.6% of the total output, mainly in injection-grade low-end products. The average export price of my country's PTFE in 2019 was US$8,549/ton.
In 2019, my country's PTFE imports were about 6,800 tons, most of which were high-end PTFE modified products to meet the needs of downstream industries. my country's PTFE has a structural overcapacity phenomenon. There is a serious surplus of injection molding grade low-end products and low capacity utilization. However, high-end varieties represented by high compression ratio polytetrafluoroethylene dispersion resins still rely on imports, and the average import price is maintained. Above 10,000 USD/ton. At present, the price of domestic PTFE low-end products is about 40,000 yuan/ton, the price of mid-end products is 40,000 to 60,000 yuan/ton, and the price of high-end products is above 60,000 yuan/ton.
