Abstract: A method for forming recess patterns in a handle of a skipping rope includes the steps of preparing materials for forming the handle and a filler made of rubber materials having a certain color, forming the recess patterns in the surface of the handle while making the handle with synthetic resins, and filling the recess patterns with the filler and solidifying the filler to form in a body with the handle. The filler is made of rubber materials and thereby it can be prevent the handle slipping from a user's hand. Further, the recess patterns can have various shapes and the filler can has various colors and thereby the appearance of the handle is beauty.

Abstract: The present invention relates to a polypropylene resin composition and more particularly, to the polypropylene resin composition comprising a high crystalline polypropylene, a polypropylene or polyethylene having low molecular weight, an inorganic filler and an anti-additive. The polypropylene resin of the present invention provides improved heat resistance, impact resistance and scratch resistance, so that it is suitable for substituting conventional polypropylenes used for automotive interior materials having several tens of grades, and further lowers manufacturing cost along with improving productivity and reclamation of used materials.
