The hottest polyamide industry is full of vitality

  • Detail

Polyamide industry is full of vitality and vitality.

in the polyamide chain, because its raw material industrial production technology has not made a major breakthrough so far, its cost and price have remained high, which makes the cost of polyamide chips much higher than that of polyester chips, seriously restricts the competitiveness of polyamide fibers, and its market growth is slow. However, due to the expansion of non fiber applications such as engineering plastics, the polyamide industry is still full of vitality and vitality, It shows the prospect of vigorous development

polyamide chain: multi head parallel

in 2004, the global caprolactam production capacity was 4390kt/A, of which the Asia Pacific region accounted for 32%, Western Europe for 25%, North America for 21%, Eastern Europe for 19%, and South America for 2%. In 2004, the global consumption of caprolactam was about 4000kt. According to the prediction of Tecnon orbi Chem, the annual growth rate of caprolactam in the world will be less than 2% by 2010, and the world production capacity will reach 4980kt/a and the output will be 4560kt in 2010. The annual growth rate of world nylon fiber demand is less than 1%, while the annual growth rate of polyamide resin consumption will be 4.3%. In 2015, the global demand for caprolactam can reach about 5000kt, of which China's demand will account for 20% of the global total

BASF, DSM and Yubu industries are the top three caprolactam producers in the world. BASF has a production capacity of 708kt/a, accounting for 16.1% of the global production capacity, and is the world's largest supplier of caprolactam; DSM of the Netherlands has a production capacity of 475kt/a, accounting for 10.8%. With a capacity of 365kt/a (110kt/a in Japan, 90kt/a in Japan, 85kt/a in Spain and 80kt/a in Thailand), Yubu Xingchan is also the largest caprolactam producer in Asia. Its production capacity is before Taiwan's PetroChina development company (240kt/a) and Toray industries. At the beginning of 2003, the company closed the 20kt/a old process production plant located in Japan and expanded the capacity of the matafu plant in Thailand by 20kt/A. The 85kt/a unit of its Spanish subsidiary PQM in castellan will also be expanded to 100kt/a by 2005

at present, the development of caprolactam in the world has the following characteristics: first, the overall supply and demand of caprolactam in the world is balanced, but the development of various regions is uneven. Second, the process of reorganization, merger and association of caprolactam industry is further accelerated, and the business concentration is getting higher and higher. Third, the consumption structure of caprolactam in the world is changing. Fourth, new installations in Russia, Eastern Europe and Mexico have developed rapidly. Fifth, the production of caprolactam in developing countries in South Korea, Thailand, India and other surrounding regions has developed rapidly

after three years of overcapacity, rising raw material prices and profit squeeze, the global adipic acid market finally began to recover from the second half of 2004 driven by the shutdown of some units and strong market demand in China. A new research report released by Tecnon orbi Chem, an internationally renowned consulting company, said that due to the limited new capacity and the rapid growth of market demand, the global adipic acid market supply will become tight in the next few years, and the market prospect is promising

the report predicts that the total demand for adipic acid in the global market will reach 2600kt/a in 2005, and the production capacity will reach 2864kt/A. the global adipic acid market demand is expected to grow at an average annual rate of 3.2% in the next five years. The demand for adipic acid of nylon 66 accounts for about 62% of the total demand, and will increase at an average annual rate of 1.9%. Among them, the demand for adipic acid of fiber grade nylon 66 is growing slowly, while the demand for engineering grade nylon 66 will grow rapidly at an average annual rate of 4%. This is mainly due to the fact that nylon engineering resin is accelerating the replacement of metal parts in the automotive industry. This change originally originated in Europe, then to the United States, and now has expanded to Japan and other Asian markets. The fastest-growing demand for adipic acid in other non nylon fields is in the production of polyurethane and polyester polyols, with an average annual growth rate of 6%; However, the demand for adipic acid in the plasticizer market grows slowly, with an average annual growth rate of only about 2%

at present, the operating rate of adipic acid plants worldwide has increased from 84% in 2001 to 90% at present. Due to the lack of new capacity, the operating rate of adipic acid plants worldwide will further increase in the next few years, which is expected to rise to 94% in 2006 and 97% in 2007

the main distribution areas of adipic acid production capacity in the world are: North America 1172kt/a, of which the United States 1002kt/A; Europe 1 124kt/a, of which France 320kt/a, Germany 408kt/a, Britain 270kt/a; The Asia Pacific region is 568kt/a, including 197kt/a in China, 1220kt/a in Japan, 135kt/a in South Korea and 114kt/a in Singapore. INVISTA is the world's largest producer of adipic acid, with a production capacity of 805kt/A, accounting for 37% of the world's total production capacity; The second is French Rhodia, whose production capacity accounts for about 18.5% of the total global production capacity

since polyamide was used as engineering plastics, the main varieties now include PA6, 66, 11, 12, 610, 612, 1010, 46, mxd-6 and all aromatic Pa. in recent years, new varieties such as 6T and 9t have been developed, which further widens the application field of PA

in 2004, the total production capacity of PA6 and PA66 engineering plastics in the world was 1878kt/a, of which the United States was 802KT/A, accounting for 42.7% of the world's total production capacity; 733kt/a in Europe, accounting for 39%; Japan 210kt/a, accounting for 11.1%; Asia (excluding Japan) 104kt/a, accounting for 9.2%. This shows that the manufacturers of PA engineering plastics are mainly concentrated in the United States, Western Europe and Japan, and their production capacity accounts for more than 90% of the world's total production capacity

according to the data provided by American Chemical Systems Corporation, the total production capacity of PA engineering plastics in the world in 2003 was 1600kt/A, and the top four companies and their share were: Du Pont company was 390kt/A, accounting for 24.4%; BASF company is 220kt/a, accounting for 13.7%; Ge Honeywell is 200kt/a, accounting for 12.5%; Rhodia company is l45kt/a, accounting for 9.1%; Other companies totaled 645kt/a, accounting for 40.3%. The leading manufacturers are comprehensive large-scale petrochemical or chemical companies with strong strength. In addition to large-scale advanced polymerization devices, they all have attached mixing plants to increase the quantity of available products and provide special products that meet the requirements of the market and users. Others include allied signal, Solutia Dow, Ube, Bayer, DSM, rodici plastics, EMS, Toray, Asahi Kasei, Mitsubishi engineering plastics, etc. There are also some independent plastic mixing plants, such as the famous American RTP and LNP companies, which can provide nylon brands with characteristics that can meet the performance requirements of users. Many varieties, flexible supply and short cycle are the characteristics of these suppliers

in terms of consumption structure, the consumption of PA6 and PA66 accounts for about 90% of the total PA, occupying a leading position. In 2001, the consumption of PA66 in the world was 740kt, slightly higher than 680kt of PA6. The consumption structure in Europe is PA6 accounting for 50%, PA66 accounting for 40%, PA11, PA12 and other homopolymer and copolymer PA accounting for 10%; The dosage of PA66 in the United States is higher than that of other varieties; Japan ranks first in PA6 consumption, accounting for 52%, PA66 accounting for 38%, PA11 and PA12 accounting for 5%, PA46 and semi aromatic PA accounting for 5%

polyamide engineering plastics are mainly injection molded, while the molding processes of PA6 and PA66 are different. PA66 is basically injection molded, accounting for 95%, and extrusion molding only accounts for 5%; PA6 injection molding accounts for 70% and extrusion molding accounts for 30%

from the perspective of demand trends, due to the large-scale auto parts and the expansion of the use of packaging film in the Asian market dominated by China, the annual growth rate of nylon 6 and nylon 66 in the world was 4%~5%. In 2004, the price of nylon raw materials soared, and the results were passed on to various nylon resin manufacturers. In the nylon resin Market in 2004, the Japanese market grew slowly, the Chinese market grew rapidly, and the European and American markets grew steadily. It is expected that the consumption of nylon resin in automobiles and packaging films will increase steadily in the future. It is estimated that by 2010, the average annual market growth rate of nylon 6 will be 4% in Japan; In China, the use of automobiles increased by 40%, and that of electronics and electrics increased by 9%. The average annual market growth rate of nylon 66: the use of automobile in China increased by 12%, and the electronic and electrical industry increased by 7-8%. It is expected that the overall nylon resin in China will grow at a rate of 10%

in 2004, the output of nylon fiber in the world rebounded significantly from the low point in 2001, jumping over the 4000kt mark again, rising to 4147kt, an increase of 4.7% over the previous year. Among them, the production of nylon filament increased by 5.3%, reaching 3700kt, but the production of nylon staple fiber decreased to less than 500kt. Prior to that, the world nylon fiber output in 2003 was only 3950kt, only 45kt higher than that in 2002, with an increase of only 0.8%. From the production situation of major countries and regions, China, India, Taiwan, China of China, the United States and Southeast Asia are among the regions that increase production. Among them, China and India have double-digit growth, with China's growth rate as high as 18.4%, India's growth rate of 13.1%, Taiwan, China of China's growth rate of 9.2%, the United States' growth rate of 3.1%, Southeast Asia's growth rate of 1.6%, Japan's growth rate unchanged from the previous year, while Europe and South Korea reduced production, Western Europe's production fell by 0.5%, and South Korea fell by 10.2%

in terms of the production of nylon polymer, in 2003, the world produced more than 6000kt of nylon polymer, of which more than 65% were nylon fibers used in the production of carpets, textiles and industry, and 2000kt were used in engineering plastics

due to the sharp rise in raw material prices and strong competition from polyester and polypropylene fibers, the world nylon fiber industry has experienced the most serious crisis in history and is being adjusted and consolidated. In the future, the world nylon fiber demand will increase at an average growth rate of 2% - 3% based on the current 4000kt. The main reason is that China's nylon textile industry continues to expand, which means that the nylon fiber industry has a good development momentum Russia, CIS countries and India have great growth potential, and the demand of South America and Brazil is strong. At present, the per capita consumption of nylon fiber in the United States and Western Europe has exceeded LKG, but only 0.4KG in the aforementioned regions, so there is a lot of room for development

according to the statistics of the U.S. Bureau of fiber economics, the world nylon fiber production capacity in 2003 was 5039kt/a, including 4460kt/a filament and 580kt/a staple. By the end of 2004, nylon fiber can increase the oxygen index value, and the production capacity will increase to about 5550kt/A. In the future, the demand for nylon fiber in the world will basically maintain a steady growth trend. The filament production will grow rapidly, with an annual growth rate of 3% to 4%. Industrial and carpet filaments will grow significantly, but textile filaments will not grow too much

the main producing countries and regions of nylon fiber are: the United States, China, Taiwan, China, South Korea and Germany. The average annual growth rate of the United States from 1990 to 2003 was -0.6%, showing a slight downward trend. Although polyester fiber is expanding, the average annual growth rate of Chinese nylon fiber from 1990 to 2003 was 14%, and the growth rate is still very prominent. Since 2003, it has replaced the position previously occupied by Taiwan, China, and now ranks second in the world. Taiwan expanded its filament production in 2000 at one stroke, but the expansion has slowed down since then. In 2004, the ranking of the top three countries or regions in the world did not change, and the output increased compared with 2003. The situation of Germany, which is in the fourth place, remained basically unchanged, and the output of South Korea, which is in the fifth place, began to decline in 2004. In Japan, due to the fierce competition between nylon and polyester, the main uses are being replaced by polyester, and the production has been shrinking for a long time. In 2003, the output fell to 127kt, and there was no change in 2004

production and demand of polyamide chain in China

at present, there are four caprolactam (CPL) production enterprises in China, including Sinopec Baling Branch, Nanjing DSM, Shijiazhuang chemical fiber and Juhua Group Company. The production of caprolactam in China has exceeded 100000 tons from 8.452kt in 1990 to 100.2kt in 1997, 200.8kt in 2003 and 228kt in 2004

although the production of caprolactam in China has increased rapidly in recent years, it still cannot meet the needs of the development of polyamide industry in China, and the import volume is not large
