Polyethylene resin foamed particles, polyethylene resin in-mold foam-molded article, and production methods thereof
Abstract:
Polyethylene resin foamed particles are obtained by foaming polyethylene resin particles containing a base resin. The base resin is a linear polyethylene resin. The polyethylene resin particles have a storage elastic modulus of 900 Pa or more and 5000 Pa or less at an angular frequency of 1 rad/second and a storage elastic modulus of 100000 Pa or less at an angular frequency of 100 rad/second, in a dynamic viscoelasticity measurement at 190° C. A differential scanning calorimetry (DSC) curve obtained by heating the polyethylene resin foamed particles using a differential scanning calorimeter at a temperature rising speed of 10° C./minute within a range of 20° C. to 220° C. has two melting peaks of a melting peak on a low temperature side and a melting peak on a high temperature side.
