| 发明名称 | Polyolefin-based resin expanded beads comprising inorganic fillers | ||
| 摘要 | An inorganic filler-containing, polyolefin-based resin expanded bead having an expanded core layer of a first polyolefin-based resin, and a cover layer of a second polyolefin-based resin that covers the expanded core layer, wherein a weight ratio of the cover layer to the expanded core layer is 1:99 to 20:80, the expanded core layer contains an inorganic filler in a weight percentage amount of 5 to 90%, and the cover layer contains no inorganic filler or contains an inorganic filler in a weight percentage amount lower than that in the expanded core layer. | ||

| 主权项 | 1. A polyolefin-based resin expanded bead, comprising an expanded core layer comprising a first polyolefin-based resin, and a cover layer that covers the expanded core layer and that comprises a second polyolefin-based resin, wherein a weight ratio of the cover layer to the expanded core layer is 1:99 to 20:80, the expanded core layer contains an inorganic filler in a weight percentage amount of 30% or more and 90% or less, and the cover layer contains no inorganic filler or contains an inorganic filler, which is the same or different from the inorganic filler contained in the expanded core layer, in a weight percentage amount lower than that of the inorganic filler in the expanded core layer. | ||
