Document Type and Number:
Japanese Patent JP7015226
Kind Code:
B2
Abstract:
To provide styrene-compounded polyethylene-based resin foam particles which can provide a foam molded body having sufficient strength and beauty of appearance.SOLUTION: Provided are styrene-compounded polyethylene-based resin foam particles comprising a polyethylene-based resin and a polystyrene-based resin as base resins. The styrene-compounded polyethylene-based resin foam particles have the following constitutions: (i) when an average bubble diameter is obtained from a cross-section photograph (about 50 to 200 times magnification) of around the center of the styrene-compounded polyethylene-based resin foam particles and large bubbles in the whole particle are confirmed by a cross-section photograph (about 20 times magnification), the upper limit of the number of large bubbles present, having a bubble diameter 3 or more times the average bubble diameter around the center is 2, and (ii) the upper limit of a content of a volatile component is 1 mass%.SELECTED DRAWING: Figure 1
