High purity 1-hexene can be used in the manufacture of fragrances, dyes and resins, as well as polymer modification. As a comonomer for the production of high value-added polyethylene, High purity 1-hexene is widely used in polymer materials, fine chemicals and pharmaceuticals. High purity 1-hexene is an important α-olefin product, mainly used as a comonomer for the production of high value-added polyethylene. The polyethylene produced by it has the advantages of high tensile strength, impact resistance, tear resistance, puncture resistance and high light transmittance, and is particularly suitable for the production of packaging films, agricultural films and large-diameter pipes.
