  • Patent number: 9976031
    Abstract: A resin composition is provided which is used as a vehicle part, for example, an intake hose material for a vehicle turbo to provide excellent durability, heat resistance, and elongation. The resin composition of the intake hose material for the vehicle turbo of the present invention includes polyamide 6, polypropylene, and an olefin elastomer rubber. The resin composition further includes an antioxidant, a heat resistance stabilizer, a lubricant, and a master batch. Accordingly, the resin composition of the present invention provides substantially improved durability, heat resistance, and elongation. In addition, mechanical rigidity and pressure resistant and cold resistant properties of the resin composition is improved, and simultaneously, a weight reduction is feasible and manufacturing cost is reduced.
