Large rotomoulded articles dedicated polyethylene resin composition

The present invention relates to a large, dedicated rotomoulded article of a polyethylene resin composition, the active ingredient comprising: a) 95-100 parts by weight of polyethylene resin, HDPE or LLDPE or a combination of both; 2) 2- crosslinkable silicone 5 parts by weight; 3) polyethylene - 1-2.5 parts by weight of a silicone compatibility agent; 4) 0.5-2 parts by weight of a crosslinking agent mixed; 5) 0.05 to 0.5 parts by weight of antioxidant; 6) fumed silica 0.1 to 3 parts by weight. The composition is excellent in processability, large rotomoulded articles having excellent low temperature impact toughness, creep resistance, and environmental stress cracking resistance to UV aging resistance, solvent resistance and other properties.
