Bayer MaterialScience has opened a new pilot facility for the manufacture of carbon nanotubes (CNTs) at CHEMPARK Leverkusen, Germany.
LEVERKUSEN, Germany - Bayer MaterialScience has opened a new pilot facility for the manufacture of carbon nanotubes (CNTs) at CHEMPARK Leverkusen, Leverkusen, Germany. The company has invested some EUR 22 million in the planning, development and construction of the facility, which is the largest of its kind in the world and has an annual capacity of 200 metric tons.
Bayer MaterialScience is looking to gain a head start in supplying the demand for a whole host of applications for multi-wall carbon nanotubes, which the company is marketing under the trade name Baytubes®. "Current forecasts predict an annual growth rate of 25 percent for carbon nanotubes. Within 10 years, the market is expected to be worth U.S. $2 billion," said Joachim Wolff, a member of Bayer MaterialScience’s Executive Committee and head of the Coatings, Adhesives, Specialties segment. "We are also expecting nanotechnology to create a total of 100,000 new jobs in the German industry in the medium term," he added.
Bayer MaterialScience has been operating a pilot facility with an annual capacity of 60 metric tons in Laufenburg in the German state of Baden-Württemberg since 2007. CNTs are manufactured from ethylene in a reactor at an elevated temperature using a catalytic process. "Under the right conditions, the next few years will see nanotechnology becoming a powerful branch of industry in Germany, offering attractive job prospects, innovative products and competitive solutions," said Kühling.
Baytubes are a highly innovative modification of carbon. They can be added to polymer matrices or metal systems as a filler or modifier to improve their mechanical strength and impart electrical properties. Potential applications for Baytubes include thermoplastic and thermoset systems and coatings. When used in coatings for ships, Baytubes ensure very high abrasion resistance. At the same time they reduce the flow resistance between the ship's hull and the water, resulting in a significant reduction in fuel consumption. Further applications for carbon nanotubes include rotor blades for wind turbines, and sports equipment such as skis, hockey sticks and surfboards.
