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/mor 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-&#x3b1;-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 &#x3bc;m or less.

Resin composition and resin product

While comprising filled minor compartments being filled with an inclusion in which a liquid makes the major component, and vacant minor compartments being filled with the air, at least one of the vacant minor compartments adjoins the filled minor compartments, and a fragile section is formed in at least one of ribs that demarcate the filled minor compartments and the adjoining vacant minor compartments. After the fragile section has fractured, shock energy can be absorbed furthermore by means of circulation resistance to the inclusion that flows from the filled minor compartments to the vacant minor compartments.

A center cluster panelis formed with a projected portionincluding an upper panelextended to a vehicle rear side and disposed at an uppermost portion thereof, a curved face panelconnected to a rear portion of the upper paneland directed to a vehicle front side by being bent from the connected portion, and a lower panelconnected to the curved face panel, extended to a front side and disposed on a vehicle lower side of the upper panel. The upper paneland the lower panelare formed such that respective wall thicknesses tand tare uniform. The wall thickness tof the upper panelis made to be thicker than the wall thickness tof the lower panel. The curved face panelis formed such that a wall thickness tthereof is equal to the wall thickness tof the upper panelat the portionconnected with the upper paneland formed such that the more proximate to the lower panelfrom the connected portion, the more thinned the wall thickness tgradually.

Provided is a blow-molded article which can be readily formed with good Gloss and with substantially no surface unevenness, even without application of surface coating, and which can be used as a finished product without further treatment. The blow-molded article has a base layer and a surface layer. The base layer is formed from a thermoplastic resin material having a melt index (MI) of about 0.05-2.0 and a flexural modulus of 1,470 MPa (15,000 kgf/cm.sup.2) or more. The surface layer is formed from a colored or transparent thermoplastic resin material having an MI of about 1-30 provided that it is higher than that of the base layer, and excellent weather resistance. The thermoplastic resins used to form the base and surface layers should be resins of the same family.
