Abstract
The present invention provides a polypropylene resin composition in a mixture of a pellet (A) and a pellet (B), which is characterized by mixing them with various inorganic fillers and additives, wherein the pellet (A) comprises a long fiber-reinforced composite resin (a) obtained via a pultrusion impregnation process, and the pellet (B) comprises a composite resin (b) that includes polypropylene and thermoplastic elastomer. The polypropylene resin composition of the present invention can directly replace thermoplastic elastomer overmolding or painting in automotive parts to which such processes are routinely applied (e.g., interior components of the vehicle), which makes it possible to simplify and reduce the cost of the production process for such parts.
