<p><P>PROBLEM TO BE SOLVED: To provide a polyethylene resin foaming particle for producing a polyethylene resin in-mold expansion molded product whose fusion level of the end part (edge part) is good, whose appearance is excellent, whose surface has no wrinkles and voids, whose surface property is excellent (whose surface is beautiful), and which has a high expansion ratio. <P>SOLUTION: The polyethylene resin foaming particle has an expansion ratio of≥10 times and≤50 times, and has two regions of a low-temperature side fusion caloric value region and a high-temperature side fusion caloric value region in a DSC curve acquired by differential scanning calorimetry (DSC) in which the temperature is raised at a temperature rise rate of 10°C/min from 40°C to 190°C, and has a minimum value in a differential curve of the DSC curve in the low-temperature side fusion caloric value region. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
