PURPOSE:To provide the titled compsn. having well-balanced properties among tear strength, rigidity and vacuum moldability, by blending PP, an ethylene/ propylene block copolymer, high-density PE and low-density PE. CONSTITUTION:10-30wt% PP having a melt flow rate of 0.2-1g/10min at 230 deg.C, 30-50wt% ethylene/propylene block copolymer having a melt flow rate of 0.2-1g/10min at 230 deg.C, 20-30wt% high-density PE having a melt flow rate of 0.3-1g/10min at 190 deg.C and 5-10wt% low-density PE having a melt flow rate of 0.3-1g/10min at 190 deg.C are blended together. |
