    Abstract: A seat core material of the present invention is a seat core material for vehicle including: a thermoplastic resin expanded bead article; and a frame member embedded in a peripheral edge portion of the expanded bead article. The expanded bead article has two or more lightening parts in an area from a center portion as seen in a front-back direction to a rear side. A through or non-through slit is provided in a continuous part between the lightening parts or an area in front of the continuous part over a distance of 100 mm or less along a vehicle-width direction of the expanded bead article. The slit is closed at both longitudinal ends.

    Abstract: The present invention provides polyolefin resin particles that are capable of producing expanded polyolefin resin beads having a favorable fine cell structure, expanded polyolefin resin beads that suffer less volume shrinkage under a high temperature environment and are excellent in recovery property on repeated compression, and a method for producing the expanded beads. The polyolefin resin particles of the present invention have a peak temperature (T1) of a melting peak on first heating in a DSC curve obtained by heating the resin particles from 20° C. to 200° C. at a heating rate of 10° C./min that is higher by 1.5° C. or more than a peak temperature (T2) of a melting peak on second heating in a DSC curve obtained by, subsequent to the first heating, cooling the resin particles from 200° C. to 20° C. at a cooling rate of 10° C./min, and then heating the resin particles from 20° C. to 200° C. at a heating rate of 10° C./min. The method for producing expanded polyolefin resin beads of the present invention includes: a step of preparing preliminary resin particles containing a polyolefin resin; a step of heat-treating the preliminary resin particles at a temperature that is higher by from 15 to 25° C. than a melting point of the preliminary resin particles, so as to produce resin particles; and a step of expanding the resin particles.
