ABSTRACT:
The present invention relates to a multimodal polyethylene composition wherein (i) the composition has an MFR2of 0.1 to 100 g/10 min, (ii) the shear thinning index SHI(1,100)and the log MFR2of the composition satisfy the following relation: SHI(1,100)≧−10.58 log MFR2[g/10 min]/(g/10 min)+12.94, and (iii) the composition has an environmental stress crack resistance ESCR of 10 h or more. Furthermore, the present invention relates to a process for the production of said composition, an injection moulded article, in particular a cap or closure, comprising said composition and to the use of said composition for the production of an injection moulded article.
