POLYETHYLENE RESIN COMPOSITION FOR CROSSLINKED FOAM, METHOD FOR PRODUCING POLYETHYLENE RESIN CROSSLINKED FOAM, AND POLYETHYLENE RESIN CROSSLINKED FOAM OBTAINED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a polyethylene resin composition for a crosslinked foam usable for practical use as a crosslinked foam as well as the one obtained by using a low-density polyethylene resin produced by an autoclave method by improving the foamability of a low-density polyethylene resin produced by a tubular method.;SOLUTION: The polyethylene resin composition for the crosslinked foam comprises 100 pts.wt. low-density polyethylene produced by the tubular method, and having 0.5-10 g/10 min melt flow rate, 910-930 kg/m³ density and 3-8 molecular weight distribution, 1-50 pts.wt. thermal decomposition-type foaming agent, 0.3-2 pts.wt. crosslinking agent and 0.1-2 pts.wt. crosslinking auxiliary.;COPYRIGHT: (C)2008,JPO&INPIT
