2 Production and Market Statistics
Abstract
Fluoropolymers are specialty plastics, an essential material in the human society for the foreseeable future of sophisticated, safe and cheaper industrial products. Fluoropolymers have unique properties including resistance to strongly aggressive chemicals and extreme hot and cold temperatures, which make them an immensely ubiquitous material all round the world. Specifically the discovery of polytetrafluoroethylene (PTFE), the largest consumed fluoropolymer, has driven the trend towards using lightweight, anticorrosive, high-resistant plastics instead contrary metals. Sustained by new developments of products, applications, and processes, as well as strong demands in new markets, the demand is expected to grow further exponentially in the forthcoming future.

Applications of PTFE; Fluoropolymers; Fluoropolymers as the future; Fluoropolymer consumption; Growing fluoropolymer market; Polytetrafluoroethylene (PTFE) Fluoropolymers are specialty plastics and have experienced growth over the decades since the discovery of polytetrafluoroethylene (PTFE) in 1938. Fluorinated thermoplastics have grown into a large family of polymers based on tetrafluoroethylene, vinylidene fluoride, and chlorotrifluoroethylene to name a few. PTFE has attracted the majority of consumption among all fluoropolymers in every industry either directly or indirectly. The drivers of the growth have resided in the end-user applications, where the unique properties and performance capabilities of these polymers are required. Fluoropolymers have many unique properties including resistance to strongly aggressive chemicals and extreme hot and cold temperatures. Other characteristics of these plastics are good weatherability, outstanding electrical and thermal insulation, ultrahigh purity, and low coefficient of friction. Fluoropolymer parts are thus used in chemical processing, automotive and aerospace industries, medical devices, wire and cable insulation, semiconductor and microelectronics manufacturing, cookware and bakeware, industrial coatings, pharmaceutical and biopharmaceuticals to name a few. The United States continues to be the market leader for consumption of fluoropolymers. Traditional uses of these plastics in chemical processing, cookware, bakeware and industrial coatings and medical devices continue growing in the US. The bulk of the growth of fluoropolymers in the late 2000s and 2010s come from fiber optic and wire and cable applications. Fluorinated ethylene propylene (FEP), polyvinylidene fluoride (PVDF), PTFE, ethylene tetrafluoroethylene (ETFE), and ethylene chlorotrifluoroethylene (ECTFE) are the fluoropolymers that are consumed by the wire and cables markets, though FEP and PVDF possess the largest volume in primary insulation and jacketing applications. Periodic economic downturns have forced the design engineers to sharpen their pencils and avoid overdesigning fluoropolymers. The availability of a variety of fluoropolymers has allowed the appropriate resin to be selected for each use. PVDF has had the fastest growth rate because of its fitness for use as a premium siding and roof coating in addition to other applications. A healthy construction sector always benefits PVDF handsomely. Aside from the North American region, fluoropolymer consumption is anticipated to grow significantly in the developing economies primarily China and India. Asian countries such as Japan, Korea, and Taiwan also continue to increase their consumption of fluoropolymers. The markets in Thailand, Vietnam, Malaysia, Singapore, and Philippines are relatively small but continue to grow. Growth in fluoropolymer consumption in the European countries has historically lagged behind both those of North America and Asian regions. It is expected to grow at a faster rate than the US in the 2012–2017 period. 2.1. Growth of Fluoropolymers
According to a 2013 study,1 the global fluoropolymer market revenue was estimated to be $7.2 billion in 2013 and is anticipated to reach $9.8 billion by 2018, growing at a compound annual growth rate of 5.7% from 2013 to 2018. Asia-Pacific and North America regions dominate the global fluoropolymer market, collectively accounting for 71.1% of the global fluoropolymer demand in 2010. Asia-Pacific is expected to be the fastest growing market for the foreseeable future. The rapid growth of industry and the rise in the living standards has led to increasing demand from the economies of China and India. The market for fluoropolymers is being driven by the expansion of existing application markets and the emergence of new markets.1 Fluoropolymers exhibit properties which are superior to those of other polymeric materials and rubber, making them ideally suitable for a wide range of applications, especially those which demand extreme environments, such as high temperature stability, high chemical resistance, superior dielectric properties, weldability, mechanical strength, etc. The automotive and transportation industry is the largest end-use application for fluoropolymers.1 The growing trend toward lower vehicle weight, lower emissions, and enhanced fuel efficiency is expected to drive the consumption growth of fluoropolymers in this sector. The high sales growth of passenger cars in emerging markets such as China and India is also expected to boost the market. The electrical and electronics industry is the second largest application for fluoropolymers where they are increasingly being used in semiconductor fabrication, wire and cable insulation, lithium-ion batteries, jacketing, etc. Emerging new applications including photovoltaic modules, fuel cells, jacketing, lithium-ion batteries, etc., would also fuel the growth of the fluoropolymer market in the near future. The durable nature and excellent performance characteristics of fluoropolymers in harsh environments and demanding applications are expected to further help the market. 2.2. Regional Consumption of Fluoropolymers
Figure 2.1 indicates North America continues to dominate the global fluoropolymer market, accounting for 41% of the overall consumption in 2010. Asia-Pacific and Europe are the second and third largest fluoropolymers consuming regions, accounting for 30 and 21% of the overall market in 2010. North America is expected to lead the consumption of fluoropolymers because of sizable demand from a number of industries such as electrical, electronic, and automotive industries. In recent years Asia-Pacific has exhibited great demand for fluoropolymers. This trend is likely to continue as a result of the fast growing economies of China, India, and other Asian countries. The cost of production of PTFE in China is relatively low as compared to the US and EU. China has the most abundant supply of fluorspar, which is the source of fluorine and main driver of fluoropolymers' cost. This preferential cost position is expected to entice both foreign and domestic manufacturers to construct PTFE production plants in China. The players in fluoropolymer industries are in pursuit of the Asia-Pacific region to enhance competitive position, market share, and profitability. The United States accounted for 20% of the world consumption of PTFE in 2012 and 40% of the world consumption of other fluoropolymers. From 2012 to 2017, US consumption of PTFE will grow at 2.0% per year and consumption of other fluoropolymers is expected to grow at an average annual rate of about 3.3%. About 67% of Western Europe's fluoropolymer consumption is PTFE. During 2012–2017, Western European consumption of PTFE is expected to grow at an average annual rate of 3.5%, while other fluoropolymers are expected to grow at an average annual rate of 6.8% during the same period. Japan is increasingly specializing in fluoropolymers other than PTFE. Japanese fluoropolymer consumption is expected to grow at an average annual rate of 5.9% between 2012 and 2017. China is the world's largest consumer of PTFE, with 36% of world consumption in 2012. China's production capacity and production of other fluoropolymers became significant in 2012. Other countries currently producing fluoropolymers include India and Russia. PTFE is the only fluoropolymer produced in India but not in Russia. It is the dominant fluoropolymer traded and consumed in the rest of the world. Consumption of fluoropolymers in countries other than the United States, Western Europe, China, and Japan (rest of the world) accounted for about 12% of world fluoropolymer consumption. PTFE consumption in these countries will increase at an average annual rate of about 5% from 2012 to 2017.
Figure 2.1 Regional consumption of fluoropolymers in 2010. (ROW, rest of the world)1 2.3. Consumption of Fluoropolymers and PTFE
A 2011 study by the Global Industry Analysts, Inc.2 states the global market for PTFE is projected to exceed 240 000 tons by the year 2017. It cites the key factors driving the emerging market as: 1. opportunities in various end-use applications; 2. increasing demand from developing markets; and 3. advancements in processing technology. PVDF and FEP follow PTFE in consumption quantities followed by other fluoropolymers such as ETFE, polychlorotrifluoroethylene (PCTFE), perfluoroalkoxy polymer (PFA), and PVDF. Figure 2.2 illustrates the breakdown of the consumption of various fluoropolymers. A 2012 report by IHS3 describes PTFE as the dominant fluoropolymer, accounting for 58% (by weight) of world fluoropolymer consumption in 2012. Other fluoropolymers include...
