PURPOSE:To obtain crosslinked polyolefinic resin foam having excellent appearance, toughness, improved moldability and processability and improved heat resistance without causing damage problems during molding at high temperature and harming appearance. CONSTITUTION:(A) 100 pts.wt. resin component composed of A1: 40-100 pts.wt. polypropylene-based resin having 0.5-12 melt index and A2: 60-0 pts.wt. polyethylenic resin having 2-50 melt index is blended with (B) 0.3-8 pts.wt., preferably 0.5-6 pts.wt. 1,2,4-benzenetricarboxylic acid triallyl ester and B2: 99.5-0.5wt.% 1,9-nonanediol dimethacrylate and (C) 1-30 pts.wt., preferably 2-25 pts.wt. thermal decomposition type blowing agent (e.g. azodicarbonamide). |
