Abstract:
A multimodal ethylene copolymer with a density of at least 940 kg/m3 having an MFR21 in the range of 1 to 30 g/10 min and a Fmax/λI ratio of less than 60 cN/s; said ethylene copolymer comprising at least three components (I) an ethylene and optionally at least one C3-20 alpha olefin comonomer component forming 30 to 60 wt % of said ethylene copolymer; (II) an ethylene and optionally at least one C3-20 alpha olefin comonomer second component forming 30 to 60 wt % of said ethylene copolymer: and (III) an ethylene and optionally at least one C3-20 alpha olefin comonomer third component forming 3 to 20 wt % of said ethylene copolymer; wherein at least one of components (II) or (III) is a copolymer.
