Polyethylene plastic production process
Journal Title: Materials Science: Materials Review - Year 2017, Vol 1, Issue 1
Abstract
Polyethylene has become the most important polyolefin plastic with excellent mechanical properties, processing properties and chemical resistance. It is used in the production of film, packaging and pipe. However, the nonpolar property and low rigidity of polyethylene limits its application in certain fields. The new progress of chemical modification, physical modification and modification of polyethylene were reviewed. Chemical modification includes graft modification, copolymerization modification, crosslinking modification, chlorination, chlorosulfonation modification and plasma modification. There are different methods of polyethylene production which include high pressure polyethylene, medium pressure polyethylene and low pressure polyethylene. All three methods have their own benefits and shortcomings which coexist in the industry.
