We know that high molecular weight polyethylene is ethylene, butadiene monomer in the role of a catalyst, polymerization of average molecular weight greater than 2 million of engineering thermoplastics. Engineering equipment UHMWPE pipe equipment very comprehensive performance by the material, long-term work at -269 to + 80 ℃ condition, known as "amazing," and ultra-high molecular weight polyethylene project plastic pipe technology in China matures, more and more use of this pipeline project has become a good performance of the new affordable engineering thermoplastics equipment. Ultra-high molecular weight polyethylene pipe equipment in 2001 was listed as the Ministry of Science and Technology National Science 056 meter word document focus on promoting national scientific and technological achievements, is a chemical class of new materials and new products. Ministry of Science and the State Planning Commission ultrahigh molecular weight polyethylene pipe device as a high-tech industrial development areas of focus of the current priority projects. The world's first company to achieve industrialization by the United States in 1957, after Germany, the United States, Japan's Mitsui Petrochemical Corporation, also put into industrial production. Our success in 1964 was first developed and put into industrial production. Development of ultra-high molecular weight polyethylene pipe equipment very quickly, before the 1980s, the world's average annual growth rate of 8.5%, after the 1980s, the growth rate as high as 15% to 20%. Moreover, China's average annual growth rate of over 30%. 1978 World consumption of 12,000 to 12,500 tons, while in 1990 the world demand of about 50,000 tons, of which the United States accounted for 70%. 2007-2009 China has gradually become the world's plastics factory, ultra-molecular-weight polyethylene industrial development is very rapid.
