PROBLEM TO BE SOLVED: To develop an olefinic resin composition for injection foaming whose composition is excellent in the moldability and gives an injection foamed body having impact resistance, and to obtain an injection foamed body thereof. SOLUTION: The olefinic resin composition for injection foaming, comprises the olefinic resin (A) and olefinic resin (B), both of which have different melt flow rates(MFR) respectively, one of which has a melt flow rate of not less than 50 g/10 min, the other of which has a melt flow rate of less than 50 g/10 min, and the difference between the MFRs of which is 20 g/10 min or more, and the resin composition contains them in the range of (A):(B)=60-99:1-40 (weight ratio); the injection foamed body is made by a general injection foaming, using the above olefinic resin composition. |
