  Provided are non-crosslinked foamed polyethylene resin particles that have a bulk density BD of 10 g/L or more and 100 g/L or less and are obtained by foaming polyethylene resin particles containing an antistatic agent in an amount of 0.1 part by weight or more and 3 parts by weight or less with respect to 100 parts by weight of a polyethylene resin and having a density of 0.920 g/cm3 or more and less than 0.940 g/cm3, and the non-crosslinked foamed polyethylene resin particles have a shrinkage ratio of 3% or more and 30% or less determined in accordance with Formula (1). The non-crosslinked foamed polyethylene resin particles can simply afford an antistatic molded non-crosslinked foamed polyethylene resin body that has a small shrinkage ratio with respect to mold dimension, is deformed in a small degree, and has good surface stretch. Shrinkage ratio = (BD-VBD) x 100/VBD (1) In the formula, BD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C and 0.1 MPa (under standard atmospheric pressure), and VBD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C under a reduced pressure of 0.002 MPa or less.

  所提供的非交联发泡聚乙烯树脂颗粒的体积密度 BD 为 10 g/L 或以上、100 g/L 或以下，是通过发泡含有抗静电剂的聚乙烯树脂颗粒获得的，抗静电剂的用量为 0.该非交联发泡聚乙烯树脂颗粒的收缩率为3%或以上，30%或以下，根据式(1)测定，其密度为0.920克/立方厘米或以上，0.940克/立方厘米以下。非交联发泡聚乙烯树脂颗粒可以简单地提供抗静电模塑非交联发泡聚乙烯树脂体，该体相对于模具尺寸的收缩率小，变形程度小，表面伸展性好。收缩率＝（BD-VBD）×100/VBD (1) 式中，BD 是非交联发泡聚乙烯树脂颗粒在 23℃和 0.1 兆帕（标准大气压下）时的体积密度，VBD 是非交联发泡聚乙烯树脂颗粒在 23℃、减压 0.002 兆帕或以下时的体积密度。

  The expanded particles of the present invention have two melting peaks on a DSC curve and are made from polyethylene resin particles which (i) contain an antistatic agent, (ii) have a storage modulus of elasticity of 900 Pa or more and 5000 Pa or less at an angular frequency of 1 rad/sec and (iii) have a storage modulus of elasticity of 100000 Pa or less at an angular frequency of 100 rad/sec, in dynamic viscoelastic behavior measurement at 190°C. From this, it is possible to provide expanded polyethylene resin particles which have a broad temperature range in molding process, and are excellent in appearance of a molded product and in physical properties (such as an antistatic property), without impairing productivity of resin particles which are a raw material of expanded particles.

  本发明的发泡颗粒在 DSC 曲线上有两个熔融峰，由以下聚乙烯树脂颗粒制成：(i) 含有抗静电剂；(ii) 在 1 弧度/秒的角频率下，存储弹性模量为 900 Pa 或更大，5000 Pa 或更小；(iii) 在 190°C 的动态粘弹性行为测量中，在 100 弧度/秒的角频率下，存储弹性模量为 100000 Pa 或更小。由此，可以提供在模塑过程中温度范围宽、模塑产品外观和物理性能（如抗静电性能）优异的发泡聚乙烯树脂颗粒，而不会影响作为发泡颗粒原料的树脂颗粒的生产率。

  Expanded polyethylene resin particles include an antistatic agent and a base resin. The expanded polyethylene resin particles are obtained by expanding polyethylene resin particles including the antistatic agent and the base resin, the polyethylene resin particles having a storage modulus of elasticity of 900 to 5000 Pa at an angular frequency of 1 rad/sec in dynamic viscoelastic behavior measurement at 190° C. and a storage modulus of elasticity of 100000 Pa or less at an angular frequency of 100 rad/sec in dynamic viscoelastic behavior measurement at 190° C. The expanded polyethylene resin particles have a low temperature side melting peak and a high temperature side melting peak on a differential scanning calorimetry (DSC) curve obtained when a temperature of the expanded polyethylene resin particles is increased from 20° C. to 220° C. at a heating rate of 10° C./min.
