medical titanium plate DuPont titanium dioxide want

DuPont titanium dioxide want to build production bases in Shandong
 The world's largest manufacturer of titanium dioxide DuPont recently disclosed that the company is negotiating with the Dongying Economic Development Zone , want to build a world-class buy titanium bar dioxide production base in the region. According to experts, one of the country 's total consumption of titanium dioxide is an important social consumption level reference mark , because titanium dioxide broad range of applications . It is the paint, plastic, ink , paper, chemical , cosmetic, pharmaceutical, food and other industries indispensable to the production of raw materials, and therefore the production of titanium dioxide has attracted increasing attention in various industrial countries. Sand and general manager of DuPont Titanium Technologies Vince DuPont vice president , said: "In the Asian market , especially in China , the current and future growth in demand for titanium dioxide faster than the rest of the world Our goal is to grow in this . the process of strategically consolidate its leading position as a major global supplier of titanium dioxide . establish new plant will greatly enhance our fast-growing markets in the ability to service customers in Dongying . " It is reported that DuPont was looking fit in Asian nations titanium dioxide production site , Dongying eventually became the site into the negotiating process . DuPont is currently the world's largest manufacturer of titanium dioxide in the United States has three production plants in Mexico and China Taiwan have a manufacturing plant, a new plant will serve the plastics in China and the Asia-Pacific region in China , coatings and paper industry. Chinese titanium dioxide industry early in the 1980s had to squeeze into the international market of titanium dioxide and titanium dioxide directly affected by the international titanium metal market fluctuations. According to the report estimated that in the next 2 to 3 years , the domestic titanium dioxide market capacity growth at least equivalent to the GDP growth rate , probably in more than 10% , will greatly exceed the global average. In 2005 the country is expected to titanium dioxide demand will reach 750,000 -80 million tons. Currently , a large number of small and medium domestic enterprises titanium dioxide production of low-end products, high-end products is still mainly rely on imports , and thus " low-end surplus , melee, high vacancies fall " situation occur within the industry . DuPont reached a production capacity of 1.2 million tons , accounting for almost global total production capacity of titanium dioxide 1/4 in the high-end market is anything they want . Domestic industry leader through a series of acquisitions of Panzhihua Iron and Steel Group , Chongqing Titanium holdings owned legal person shares 5580 shares to 29.8% stake to become the largest shareholder of Chongqing Titanium , and at the end of last year will be renamed Pan Yu Titanium Chongqing Titanium . The report noted that with Mrs help companies successfully landed in China, the country is about to kick off in a battle of titanium dioxide .
