A running board made of a TPP material comprises the following substances: 100 parts of polypropylene, 2.4 parts of an antioxidant, 9.7 parts of an antistatic agent, 10 parts of carboxylic nitrile rubber, 21 parts of silicon dioxide, 21 parts of polysulfide rubber, 10 parts of polyketone resin, 23 parts of nano-level calcium carbonate, 25 parts of propylene glycol and 9 parts of polyether. In order to meet requirements, the surface hardness of the TPP running board reaches HRB 56-60, and the tensile strength reaches 76-80 MPa. The surface of the TPP running board is polished. The TPP running board is used on the running machine, the shortcoming that the traditional running board is broken easily, is poor in elasticity, large in noise and short in service life and the like is overcome, the weight of the running machine is reduced integrally, then later costs for conveyance, labor and the like are reduced, the thickness of the running machine is greatly reduced, the attractiveness is improved, meanwhile, the running machine is foldable, the thickness of the running machine can be reduced to a great extent, and the running board can be stored in a family conveniently.
