Polyethylene powder, method for its production and use in rotational molding

摘要

Polyethylene powder comprising at least one additive having: Melt Flow Index (MFI), measured at 190° C. with a load of 2.16 kg in accordance with standard ISO 1133-1:2011, ranging from 0.1 g/10 minutes to 100 g/10 minutes, preferably ranging from 5 g/10 minutes to 35 g/10 minutes; density ranging from 0.890 g/cm3 to 0.965 g/cm3, preferably ranging from 0.940 g/cm3 to 960 g/cm3; bulk density ranging from 0.35 g/cm3 to 0.60 g/cm3, preferably ranging from 0.40 g/cm3 to 0.50 g/cm3; average particle diameter (d50) ranging from 400 μm to 800 μm, preferably ranging from 450 μm to 780 μm. Said polyethylene powder comprising at least one additive can be advantageously used in rotomolding.
