RESIN COMPOSITION HAVING EXCELLENT SURFACE SMOOTHNESS |
| 摘要 |
Solved is the following problem: a polyolefin resin including a film grade ethylene-α-olefin copolymer is excellent in economic efficiency, but has a narrow molecular weight distribution in consideration for strength and heat sealability, and therefore causes surface roughening to occur when applied to a covering material for an insulated electric wire or cable. Used is a polyolefin based resin composition in which, when the ratio (I10/I0.5 ) of the melt flow rate (MFR) (I10) measured at 190° C. and a load of 10 kg to the MFR (I0.5) measured at 190° C. and a load of 0.5 kg is defined as MFRR, MFRR≧43 is satisfied. |

1. A polyolefin based resin composition for covering insulated electric wire and cable, wherein, when a ratio (I10/I0.5) of a melt flow rate (MFR) (I10) measured at 190° C. and a load of 10 kg to an MFR (I0.5) measured at 190° C. and a load of 0.5 kg is defined as MFRR, MFRR≧43 is satisfied. |
