Pre-foamed beads of polyethylene-base resin.

摘要

Pre-foamed beads of a polyethylene-base resin are disclosed. The polyethylene-base resin has been obtained by crosslinking a starting polyethylene-base resin having a density greater than 0.940 g/cm<3> and the pre-foamed beads have a crosslinking degree of 10-45% gel content. The prefoamed beads can provide a molded articles having excellent rigidity and dimensional accuracy and showing superb dimensional stability under heat.
