Patent ID: 8207266

Claim:
A blow molded panel comprising: a resin composition for blow molding, said resin comprising: 0 to 30 weight parts of an inorganic filler based on 100 weight parts of a resin composition, said resin composition comprising a blend of polypropylene resin and high density polyethylene resin comprised of: 20 to 95% by weight of said polypropylene resin, said resin composition having a Melt Flow Rate of 0.05-2, said polypropylene resin having a melting point evaluated by a differential scanning calorimeter (DSC) of 160° C. or higher and a tensile break elongation measured at −30° C. of not less than 50%, the polypropylene resin being comprised of a propylene-ethylene block copolymer having an ethylene content of 6 to 15% by weight; and 5 to 80% by weight of high density polyethylene resin having a melting point evaluated by a differential scanning calorimeter (DSC) of 130° C. or higher, said polypropylene resin having a ratio (MFR ratio) obtained by dividing a melt flow rate determined at a temperature of 210° C. under a load of 211.8N by a melt flow rate determined at a temperature of 210° C. under a load of 21.18N is 120 or less; and said resin composition having a tensile break strength is 250 Kg/cm 2 or more at ambient temperature, and the tensile break elongation is 500% or more said resin composition being formed into said blow molded panel.
