FIELD: moulding.
SUBSTANCE: invention relates to a cross-linkable composition for rotational moulding, as well as to products obtained by rotational moulding. Composition contains at least one high density polyethylene (HDPE), at least one linear low density polyethylene (LLDPE), at least one cross-linking agent selected from organic peroxides, and at least one crosslinking agent selected from allyl compounds. While the high density polyethylene (HDPE) and linear low density polyethylene (LLDP) have the same value of the melt flow index (MFI), measured at 190 °C with a load of 2.16 kg in accordance with ISO 1133-1:2011.
EFFECT: cross-linkable composition according to the invention has improved mechanical properties, in particular, elongation at break and Izod impact strength.
