<p>Bimodal high density polyethylene composition for producing moulded articles comprising
- an ethylene homopolymer or an ethylene alpha-olefin copolymer which is a bimodal high density polymer (COMPONENT A) in combination with
- an alpha nucleating agent (COMPONENT B),
- a slip agent being a primary fatty acid amide, (COMPONENT C) and
- one or more additives selected from antioxidants, acid scavengers, pigments and UV-stabilisers(COMPONENT D),
the composition showing an increased the crystallisation temperature and a decreased coefficient of friction compared to a bimodal HDPE composition prepared with the sole use of nucleating agent and compared to the sole use of a slip agent;
and its use for producing injection moulded articles, especially caps and closures.</p> |
