Abstract
A resin composition is provided which is improved in fluidability, stiffness and impact resistance and therefore can achieve the reduction in wall thickness of a resin product for automotive interior/exterior applications comprising a polypropylene resin; and a resin product produced from the resin composition.The resin composition comprises 30 to 65 mass % of an ethylene-propylene block copolymer having a melt flow rate of 60 to 120 g/10 minutes and a Charpy impact strength of 3 kJ/m2 or more; 0 to 25 mass % of a homopolypropylene resin having a melt flow rate of 10 g/10 minutes or more and a modulus of elasticity of 2000 MPa or more; 5 to 20 mass % of an ethylene-α-olefin copolymer rubber having a Mooney viscosity of 20 to 75 or a styrene-ethylene butylenes-styrene copolymer having a styrene component content of 15 to 30 mass %; and 23 to 37 mass % of talc having an average particle diameter of 8 μm or less.
