It is an object of the present invention to provide anpolyolefin resin composition excellent in flame retardancy,nin particular capable of manifesting excellent flamenretardancy owing to a shape retaining effect uponncombustion, and excellent also in mechanical strength andnthermal characteristics, a thermoplastic resin for cablenjacketing or sheathing which comprises the above resinncomposition, and an insulated cable. n The present invention relates to a polyolefin resinncomposition comprising n 100 parts by weight of a polyolefin resin and 0.1 ton100 parts by weight of a layered silicate, n wherein a combustion residue thereof obtained byncombusting said polyolefin resin composition by heating forn30 minutes under heating condition of 50 kW/m 2 shows anyield point stress of not less than 4.9 × 10 3 Pa whenncompressed at a rate of 0.1 cm/s. |
