Chemical classification of polyethylene (POLYETHYLENE, Yinchuan coal bin liner, PE) is a polymer formed by the polymerization of ethylene, the product has been in development for about 60 years, the world's first five generic production of polyethylene resin Habitat. Polyethylene according to the polymerization method, low molecular weight, different chain structures, from high-density polyethylene, low density polyethylene and linear low density polyethylene. LDPE (LOW DENSITY POLYETHYLENE, power plant coal bunker liner, LDPE), commonly known as high-pressure polyethylene, due to lower density, the softest material, coal bin liner, mainly used in plastic bags, agricultural film. [2] High-density polyethylene (HIGH DENSITY POLYETHYLENE, HDPE), commonly known as low-pressure polyethylene, with LDPE and LLDPE contrast, a higher the temperature, oil resistance, vapor permeability and resistance to environmental stress cracking resistance, in addition to electrical insulation and impact resistance and cold can be good, wear coal bin liner, mainly used in blow molding, injection molding and other fields. Performance is based on a polymer material polymerized vinyl monomer. Polyethylene is synthesized in 1922 by the British ICI, 1939 began the industrial production, the industrial production in the United States formally, war with insulating material and military supplies as an important radar, war, Mitsui Petrochemical, Sumitomo Chemical (1958) begin full production in 1975, 14 years factory with an annual output 1.407 million tons, second only to the United States. In 1933, the British Imperial Chemical Industries has found ethylene at high pressure can be polymerized to form polyethylene. This method of industrialization in 1939, known as high-pressure process. K. Ziegler Federal Republic of Germany in 1953 found that TiCl4-Al (C2H5) 3 as a catalyst, ethylene at a lower pressure can also be polymerized. This method by the Federal Republic of Germany Hearst Corporation put into industrial production in 1955, known as the low pressure polyethylene polyethylene ene. The early 1950s, the United States Phillips Petroleum Company discovered chromium oxide - alumina gel as a catalyst in ethylene polymerization pressure can generate high-density polyethylene, and industrial production in 1957. 1960s, DuPont Canada began α- olefins ethylene and low-density polyethylene with a solution into the legal system. In 1977, Union Carbide and Dow Chemical Company has used the legal system into a low-pressure low density polyethylene, linear low density polyethylene is called, in which Union Carbide Corporation fumed most important. Linear low density polyethylene and low-density polyethylene similar performance, but both the number of characteristics of high-density polyethylene, combined with low energy consumption in production, and therefore the extremely rapid development, has become one of the new synthetic resin is the most impressive.
