The most comprehensive nylon representative enterprises in the history.The representative enterprise of Nylon 6 : BASF
This lightweight material is often used as a metal substitute, not only to reduce weight and cost, but also to provide better design flexibility for better components and products. In the 1940s, DuPont led the development of materials science, transforming nylon fiber into engineering polymer. During this period, nylon developed exponentially. Nowadays, nylon, as a kind of engineering plastics, has been widely used in all kinds of automobile parts in the world, such as intake system pipe, engine cylinder cover, charge air cooler, transmission parts and radiator tank end cover. In electrical and electronic systems, nylon is also widely used in sealing, sockets, terminal blocks, circuit breakers, switches and relays. The main varieties of nylon are nylon 6 and nylon 66, which are absolutely dominant, followed by nylon 11, nylon 12, nylon 610, nylon 612, nylon 1010, nylon 46, etc., and the new varieties are nylon 6T, nylon 9t, etc. It is understood that the global nylon production has not changed greatly in recent years. Thanks to the gradual closure of production capacity in the European, American and Japanese markets, the trend of nylon transfer to Asia is quite obvious in recent years. The production bases of Mitsubishi Chemical in Japan, Braskem in Brazil and LANXESS in Belgium have all exited the nylon production field.
The representative enterprise of Nylon 6 : BASF
BASF is one of the largest chemical plants in the world. BASF Group has more than 160 wholly-owned subsidiaries or joint ventures in 41 countries in Europe, Asia and North and South America. Headquartered in Ludwigshafen on the Rhine, the company is the largest chemical product base in the world. In 2003, BASF and Honeywell carried out asset replacement, Honeywell acquired BASF's fiber business, and BASF took over Honeywell's engineering plastics business, including Rudolph's Nylon 6 production unit. In 2009, BASF announced that it would restructure the nylon 6 business in Europe, including permanently closing the nylon 6 production plant in ludor plant in Thuringia, Germany, by the end of 2010, and concentrating the nylon 6 production in the integrated bases of Antwerp in Belgium and Ludwigshafen in Germany. In 2013, it was reported that BASF plans to build a new large nylon resin factory in Shanghai, which is located in Shanghai chemical industry zone and will produce Ultramid brand nylon, with an estimated annual capacity of 220 million pounds. BASF has nylon polymerization plants in Germany, Texas, Belgium and Brazil. BASF's construction of nylon factory in China will highlight the contradiction between supply and demand in domestic nylon market, and the price of nylon will be hit again.
The representative enterprise of Nylon 66 : INVISTA
In 1938, DuPont first industrialized nylon 66. Since then, nylon 66 has been greatly expanded in the form of fiber. In 2004, a subsidiary of Koch industries acquired INVISTA (formerly DuPont textile and interior trim) from DuPont and merged INVISTA with Kosa. Kosa is a producer of commodities and specialty polyester fibers, polymers and intermediates. It became a related company of Koch in 1998. At present, INVISTA is the largest manufacturer of chemical fiber and intermediate fiber in the world. INVISTA accounts for about 40% of the global nylon 66 polymer production capacity, and more than 75% of the global existing adiponitrile production capacity is using the proprietary technology of INVISTA. In 2014, INVISTA's new production base of hexanediamine and nylon 66 polymer was founded in Shanghai Chemical Industry Park. The new production base will be completed and put into operation this year, forming an annual production capacity of 215000 tons of hexanediamine and 150000 tons of nylon 66 polymer. It is worth mentioning that INVISTA also plans to build an adiponitrile production plant with an annual production capacity of 300000 t in the future, which is expected to be put into production between 2018 and 2019.
The representative enterprise of Nylon 11 : akoma (atofina)
As early as 1947, French atofina company began to use natural castor oil as the main raw material to produce nylon 11, and in 1955 began to gradually promote its application in automobiles. So far, in the world's top eight automobile manufacturers, 80% of their automobile brake pipes use nylon 11. Because nylon 11 can only be produced with natural castor oil, which has certain limitations, atofina company began to use oil to produce nylon 11 substitutes in 1970, and supplied nylon 12 in batches in 1973. Akoma is a company with stable production, market and R&D capabilities inherited from atofina. Since its establishment in 2004, when total restructured its chemical functional departments and derived ethylene chemicals, industrial chemicals and special chemicals, akoma has become a world-class chemical product manufacturer. Akoma has established a factory in China to produce nylon 11. Rilsan? Series products are the brand name of their nylon 11 products. Their Chinese name is Li Xuan. Akoma's biggest feature is that the nylon 11 produced is made of castor oil, which is an environmental friendly thermoplastic material, including particles and powders in various forms. It is understood that only akoma in the world can produce nylon 11 with castor oil as raw material, which is absolutely the first-class technology in the world. In addition to environmental protection, akoma rilsan? Series nylon 11 also has very good product performance, such as corrosion resistance, wear resistance, impact resistance, high elasticity, cavitation resistance, small specific gravity, aging resistance and so on.
