Abstract
A resin composition for intake hoses is provided. The resin composition includes a predetermined amount of polyester elastomer incorporated into a polyamide resin and a polypropylene resin and further includes an antioxidant, a heat stabilizer, a lubricant and a master batch if necessary, thereby exhibiting excellent durability, heat resistance, elongation, mechanical rigidity, pressure resistance and cold resistance, and reducing weight and production costs.
