Abstract: A composition of polypropylene composite resin having high impact strength and high adhesion is provided. The composition of polypropylene composite resin having high impact strength and high adhesion can largely enhance base adhesion and impact resistance due to a high friction coefficient while providing a similar mechanical property to the related art. The compositions provided herein include mixing a polypropylene polymer, a polyethylene resin composition, and a thermoplastic elastomer, a silane-based propylene polymer, and an inorganic filler as main components at a specific content ratio. The compositions have advantages including process simplification, cost reduction, and eco-friendly without a separate adhering process. Such compositions can be used for interior components such as sun visors, door trims, pillar trims of vehicles and various other industrial components and materials.

Abstract: Compositions of high-rigid polypropylene composite resin are provided herein. Such compositions having excellent tactile sensation and dimensional stability, and more particularly, the compositions of polypropylene composite resin having excellent tactile sensation such as thermoplastic rubber, excellent impact strength and rigidity, and low shrinkage anisotropy. The compositions of polypropylene composite resin provided herein also have excellent impact strength and rigidity as well as excellent tactile sensation such as a thermoplastic rubber and low shrinkage anisotropy. Thus, they exhibit excellent moldability and the compositions can be molded into a vehicle component. Furthermore, the compositions of polypropylene composite resin have excellent tactile sensation and can be used as a high-quality material that does not require separate painting and maintains excellent physical properties and dimensional stability as a vehicle component.

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.
