Title:
ポリエチレン系樹脂発泡粒子およびポリエチレン系樹脂型内発泡成形体およびその製造方法
Document Type and Number:
Japanese Patent JP6547628
Kind Code:
B2
Abstract:
To provide polyethylene resin foamed particles capable of producing foamed particles without impairing a productivity of resin particles, which are a starting material of foamed particles, and capable of producing a polyethylene resin in-mold foam-molded article having a broad mold-processing temperature range and good appearance, even if the foamed particles have a narrow temperature difference between the two endothermic peaks on a melting curve, obtained by a differential scanning calorimetry (DSC), by using, as base resin, a polyethylene resin having 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 90°C.
