  • Patent number: 10899858
    Abstract: Provided is a polyethylene material and application thereof. A density distribution of the polyethylene material is in a range of 0.880 g/cm3-0.960 g/cm3. An amount of a fraction at a temperature of 40° C. obtained by conducting temperature rising elution fractionation on the polyethylene material is in a range of 9.0 wt %-40.0 wt %, preferably in a range of 10.0 wt %-25.0 wt %, more preferably in a range of 9.9 wt %-20.0 wt %. A melting temperature of the polyethylene material is 110° C.-135° C., preferably 116° C.-130° C. The polyethylene material provided by the present application has distinctly improved amount of medium/low-molecular-weight fractions and high-degree-branching fractions, as well as relatively high-molecular-weight fractions which are highly branched. The polyethylene material thus has a relative high melting temperature.
