Wear resistant, flame-retardant composition and electric cable covered with said composition

摘要

The present invention relates to a resin composition comprising: (a) 30 to 90 parts by mass of polyethylene having a melt flow rate (MFR) of about 5g/10 min at the most and a density of at least 0.930; (b1) 5 to 65 parts by mass of olefin type polymer containing intra molecular oxygen atoms; (c) 5 to 40 parts by mass of at least one type of polymer selected from the group consisting of (c1) acid modified olefin polymers containing intra-molecular oxygen atoms, (c2) acid modified styrene type thermoplastic elastomers, (c3) acid-modified polyethylenes having a density of about 0.920 at the most, and (c4) acid modified rubbers, with the proviso that the total of components (a), (b1) and (c) represents 100 parts by mass; and (d) 30 to 250 parts by mass of metal hydroxide.
