Polyethylene

Low-molecular-weight substances are generally colorless, odorless, tasteless and non-toxic liquids. The pure product of high molecular weight is a milky white waxy solid powder. Low molecular weight: insoluble in water, slightly soluble in turpentine, petroleum ether, toluene, etc. High molecular weight is insoluble in known solvents at room temperature, but it can swell when in prolonged contact with aliphatic hydrocarbons, aromatic hydrocarbons and halogenated hydrocarbons. It is slightly soluble in toluene, amyl acetate and other substances at temperatures above 70â??. Polyethylene can be processed into films, wire and cable sheaths, pipes, various hollow products, injection molded products, fibers, etc., and is widely used in agriculture, packaging, automobiles and other industries. 2.PE can be used to produce high-impact plastic profiles and rubber additives. 3. It can be used as packaging material for industrial and agricultural products and food, as a covering film for crop seedlings, and as an anti-seepage film for channels and reservoirs, etc. 4. It can be used in the food industry as a chewing aid for chewing gum.
