Title:
ポリオレフィン系樹脂積層発泡シート
Document Type and Number:
Japanese Patent JP5425318
Kind Code:
B2
Abstract:
The present invention is a laminated foam sheet obtained by performing lamination using a co-extrusion method in which an annular die is used, such that at least one surface of a polyolefin resin foam layer has an anti-static layer as a surface layer; the anti-static layer comprising no less than 25 wt% to less than 70 wt% of a thermoplastic resin and more than 30 wt% to no more than 75 wt% of a polymeric antistatic agent (the sum of both being 100 wt%), the melt viscosity of the anti-static layer at 190°C and a shear rate of 100s-1 being 250 Pa·s or higher, the laminated amount of the anti-static layer being a basis weight of 5 g/m2 or more per side of the foam layer, and the initial static voltage when 10 kV is applied to the anti-static layer surface for 30 seconds being 50V or less. The laminated foam sheet exhibits exceptional static electricity dissipation performance and has exceptional heat moldability.
