Ultra high molecular weight polyethylene
Sep 14, 2016

Ultra high molecular weight polyethylene (uhmw-PE), is a linear structure has excellent comprehensive properties of Engineering Thermoplastics.

Its development very quickly, before the 80 's, average annual growth rate of 8.5% the world and into the 80 's, as much as 15%~20% per. While China's average annual growth rate of more than 30%. 1978 world consumption of 12,000~12,500 tons, and by 1990 the world demand of about 50,000 tons, the United States accounted for 70%. China becoming the world's plastics factory in 2007-2009, ultra-high molecular weight polyethylene is very fast-growing industry, the following history:

The 30 's of the last century was first raised on basic theory of ultrahigh molecular weight polyethylene fibers;

Gel spinning and plasticized spinning appear to make major breakthroughs in technology of ultra high molecular weight polyethylene;

The 70 's of the last century, United Kingdom Leeds Capaccio and Ward first developed a molecular weight of 100,000 of the high molecular weight polyethylene fibers;

1964, China successfully developed and put into industrial production;

1975 Netherlands using decalin solvents inventions gel spinning method (Gelspinning), UHMWPE fiber was successfully synthesized and patented in 1979,. After ten years of hard work and research, confirmed gel spinning method is effective way to manufacture of high strength polyethylene fiber, characterized by industrialization prospects;

1983 Japan gel squeeze ultra-drawing method, paraffin wax are used as solvents, production of ultrahigh molecular weight polyethylene fibers;

Ultra high molecular weight polyethylene pipe in China in 2001 by the Ministry of science and technology National Science Word counting (2000) document No. 056 listed as national key scientific and technological achievements promotion program, belongs to the chemical materials and products. State Planning Commission, Ministry of science and technology of ultra high molecular weight polyethylene pipe as the current priority projects in key areas of development of high-tech industries.
