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.

Resin compositions for intake hoses of turbo engines with enhanced thermal resistance

The present invention provides a polyamide resin composition comprising a resin of polyamide and polyacrylate mixed with a compatibilizer, an inorganic nucleating agent, a glass fiber, an antioxidant, an anti-hydrolysis agent and a lubricant in a predetermined ratio, which shows superior mechanical strength and heat resistance and improved glycol resistance and visibility maintenance, thus being useful in such a field that requires the aforementioned properties, for example in an automobile coolant reservoir tank.
