Polyethylene is the most widely used synthetic resin in China

which is used to produce films

cables

injection products

coatings

fibers and tubes. In recent years

polyethylene industry developed rapidly in China. However

high added value products are unable to meet growing domestic demand

which need a great deal of import

such as bimodal polyethylene. Bimodal polyethylene is a special resin with a good balance between processability and mechanical properties

which has been one of the most promising high performance polyolefin. In this article

structure and properties and production process of bimodal polyethylene were reviewed. Regulation methods of bimodal polyethylene product were briefly introduced.
