Crosslinkable composition comprising polyethylene and use thereof for rotational molding

Abstract

Crosslinkable composition comprising: (a) from 80% by weight to 98% by weight, preferably from 85% by weight to 95% by weight, of at least one high density polyethylene (HDPE); (b) from 2% by weight to 20% by weight, preferably from 5% by weight to 15% by weight, of at least one linear low density polyethylene (LLDPE); (c) from 0.2 parts by weight to 1.5 parts by weight, preferably from 0.5 parts by weight to 0.8 parts by weight, with respect to 100 parts by weight of (a)+(b), of at least one crosslinking agent selected from organic peroxides; (d) from 0.2 parts by weight to 2.5 parts by weight, preferably from 0.5 parts by weight to 1.0 parts by weight, with respect to 100 parts by weight of (a)+(b), of at least one co-crosslinking agent selected from allyl compounds. Said crosslinkable composition can advantageously be used in rotational molding (“rotomolding”).
