To provide a grab rail flexible and excellent in abrasion resistance, excellent in molding processability, such as processability of extrusion and injection molding, and especially excellent in transferability of emboss when injection-molded.
This grab rail is molded by using a thermoplastic elastomer composition obtained by adding at least one of the component selected from a group comprising (f) 0.01-1 pt.wt. of a higher fatty acid amide, (g) 0.5-10 pts.wt. of a polyorganosiloxane, and (h) 0.5-15 pts.wt. of an acrylic-silicone copolymer resin to 100 pts.wt. of an elastomer composition comprising (a) 10-70 wt.% of a thermoplastic elastomer which is formed by dispersing a partially or completely crosslinked rubber into a polyolefin-based resin, (b) 5-40 wt.% of a hydrogenated derivative of block copolymer which is expressed by the general formula of A-B-A and has characteristics (i) a melt-mass flow rate(MLMFR) of ≤0.1 g/10 min (when measured at 190°C under a load of 211.68N) and (ii) a content of the polymer block B in the block copolymer of 60-90 wt.%, and (e) 20-50 wt.% of a mineral oil-based softening agent for rubber.
