To provide a polyolefine resin composition which has strength, impact resistance, heat resistance and stiffness, can be used for a car wheel cover to be free from transformation, shrinkage and defect in loading stability, is excellent in coatability and has excellent property to bring about no projection phenomenon along a weld line.
The polyolefine resin composition comprises 40-75 wt.% of a supercrystalline olefine resin, 3-25 wt.% of a polyolefine elastomer, an inorganic filler, especially a glass bead having a particle size of 15-45 μm, 5-30 wt.% of barium sulfate having a particle size of 0.5-1 μm, and an additive component if necessary to make the total up to 100 wt.%, wherein the supercrystalline olefine resin has a melt index of 10-80 g/10 min and contains a homo-part having an isotactic pentad percent of 96% or more.
