Abstract
Expanded beads are those including a mixture of an olefin-based thermoplastic elastomer and a polyethylene-based resin, wherein a melt flow rate MFR(I) of the olefin-based thermoplastic elastomer is 2-10 g/10 min; a difference ((MFR(II))−(MFR(I))) between a melt flow rate MFR(II) of the polyethylene-based resin and the melt flow rate MFR(I) of the olefin-based thermoplastic elastomer is 1-35 g/10 min; and a content of the polyethylene-based resin in the mixture is 3-40% by weight.
Claims9
Expanded beads comprising a mixture consisting of 60 to 97% by weight of an olefin-based thermoplastic elastomer and 3 to 40% by weight of a polyethylene-based resin, said olefin-based thermoplastic elastomer having a melt flow rate MFR(I) and said polyethylene-based resin having a melt flow rate MFR(II), wherein MFR(I) is 2 to 10 g/10 min and a difference [MFR(II)−MFR(I)] between MFR(II) and MFR(I) is 1 to 35 g/10 min.
