Application for exemption from EU REACHPFAS control for soluble polytetrafluoroethylene Subject: Application for permanent exemption of soluble polytetrafluoroethylene Basis: First, soluble polytetrafluoroethylene has excellent chemical stability, physical and mechanical properties, electrical insulation, lubricity, non-viscosity, aging resistance, nonflammability and thermal stability. Second, soluble polytetrafluoroethylene is widely used in construction, chemical, machinery, medical and other fields. Third, with the rapid development of related industries such as automobiles, air conditioning, electronic information, machinery, new energy and other strategic emerging industries, soluble polytetrafluoroethylene provides a broad development space for the downstream market. SubmitterTong lI Emaillitong@dongyuechem.com Submission Date: August 22, 2023 The copolymer of tetrafluoroethylene (TFE) and perfluoropropyl vinyl ether (PPVE), referred to as PFA, is also known as soluble polytetrafluoroethylene. The biggest advantage of PFA is that it can be processed by melting and can be processed by conventional thermoplastic resin processing methods. According to the product form of soluble polytetrafluoroethylene (PFA), it can be divided into PFA resin particle, PFA powder and PFA suspension. PFA resin belongs to the main production applications in the market, accounting for a large market share, in 2021 PFA resin particles accounted for 81.61% of global sales, the market size of 291.80 million US dollars, accounting for about 80.67% of the world. PFA is widely used in the chemical industry, electronic and electrical equipment, precision equipment and other fields, with the development of downstream industry, PFA market demand is rising rapidly, and the market scale is expanding. It has excellent chemical stability, physical and mechanical properties, electrical insulation, lubricity, non-viscosity, aging resistance, nonflammability and thermal stability. From different applications, PFA mainly includes the following aspects: 1, pipe and parts: PFA Teflon pipe has excellent chemical resistance, corrosion resistance to all chemicals, the coefficient of friction is the lowest in plastics, and good electrical properties. PFA pipe has excellent stress cracking resistance and bending life, but the permeability is not as good as PTFE. The metal ion content of PFA tube is very low, and it can maintain strong mechanical strength and burst pressure at high temperature. Its chemical purity meets FDA requirements and can withstand temperatures up to 260 C. 2Seals and wear-resistant parts: PFA seals and wear-resistant parts include wear-resistant high and low temperature modified seal products. 3, wires and cables: PFA wires and cables can be used in high and low temperatures and various harsh environments for electrical connections of electrical appliances, instruments and equipment. With a wide range of temperature, oil resistance, wear resistance, acid and alkali resistance and various chemical agents, aging resistance, no burning and other excellent properties, can protect the wire in extremely harsh environment safe use. PFA insulation can be used for a long time in the electronic and electrical field where the ambient or conductor temperature is less than 260 C, and the short-term temperature can reach 300 C. It can also be used in systems with current overload or mechanical pressure, especially for instruments and electronic equipment with limited installation space and sensitivity to weight. 4, semiconductor industry: In the semiconductor industry, PFA is one of the main materials for the production of silicon chip carriers, pipes and their accessories, and semiconductor parts. For example, due to the strong corrosion of hydrofluoric acid, the lining material of high-purity hydrofluoric acid production equipment generally uses PFA; Because PFA is not susceptible to particulate contamination and has a high surface cleanliness,Wet process fluid heating for manufacturing chips; Some raw materials in the semiconductor industry are inflammable, explosive and highly corrosive dangerous goods, and PFA is one of the most commonly used materials for packaging and transportation. In addition, PFA can also be used as the lining material of semiconductor sheet carrier, pharmaceutical liquid tube, joint, bottle and tank, etc., which is widely used in semiconductor manufacturing. 5, other: PFA is widely used in construction, chemical industry, machinery, medical and other fields, mainly used in the production of corrosion resistant parts, wear resistance parts, seals, insulation parts and medical equipment parts, high temperature wire, cable insulation layer, anticorrosion equipment, sealing materials, pump valve bushing, and chemical containers. From the perspective of product market application, PFA is widely used in construction, chemical industry, machinery, medical and other fields, mainly used in the production of corrosion-resistant parts, wear reduction wear parts, seals, insulation parts and medical equipment parts, high temperature wire, cable insulation layer, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers. PFA pipes and parts are the most important downstream applications, in 2021, the world's approximately 3,754 tons, accounting for 39.6% of sales volume fusing polytetrafluoroethylene for PFA pipes and parts. In terms of manufacturers, globally, soluble polytetrafluoroethylene (PFA) core manufacturers mainly include Kemu, Daikin, Solvay, AGC and 3M. In 2021, the world's first echelon manufacturers mainly include the United States Comus and Japan Daikin, and the first echelon occupies about 60.93% of the market share; The second tier of manufacturers are Belgium's Solvay, Japan's AGC, 3M of the United States and China's Juhua shares. In 2021, the global soluble polytetrafluoroethylene (PFA) market size reached 361.72 million US dollars and is expected to reach 455.37 million US dollars in 2028, with a compound growth rate (CAGR) of 3.34% in 2021-2028. In particular, with the rapid development of related industries such as automobiles, air conditioners, electronic information, machinery, new energy and other strategic emerging industries, as well as the continuous expansion of fluorine chemical application fields, soluble polytetrafluoroethylene (PFA) provides a broad market space for fluorine chemical products.
