Polypropylene has been widely applied in fields of packing agriculture building automobile, electrical equipment et al. There are a lot of types auto spare parts those are used PP. Bumpers are one of the primary parts. But the disadvantages of low rigidity, low strength and low toughness seriously limit their further applications in fields of high-performance structural materials. So Polypropylene should be strengthened and toughness. In this paper, PP as fundamental resin was toughed by elastomeric of polyolefin elastomeric (POE) as primary toughness agent, polyethylene 7042 as toughening agent, talcum (talc) as filler and calcium carbonate for the Special Compound of Car bumper by extrusion technology on twin-screw extruder. And the contents influence the mechanical performance of the Special Compound of Car bumper. The results show that he optimum processing parameter and formulation for the Special Co
