NOVELTY - Polymer resin blend composition comprises: a first polymer resin comprising polyethylene-polypropylene copolymer and graphene, where a melt index of the first polymer resin (at 230 degrees C) is 50-70 g/10 minutes as measured according to ASTM D-1238; and a second polymer resin comprising polyethylene-polypropylene copolymer and fiber reinforcing material, where the second polymer resin has melt index (at 230 degrees C) of 50-70 g/10 minutes measured according to ASTM D-1238. USE - The polymer resin blend composition is useful as resin molded article e.g. car fenders, tail gate, bonnet and electronic components, for manufacturing automotive exterior (all claimed). ADVANTAGE - The polymer resin blend composition: has a surface resistance of less than or equal to 103 Omega /square, and a specific gravity of less than 1.1 g/cm3 (claimed), exhibits improved elasticity, flexural modulus and flexural strength; and provides the automotive exterior having excellent workability, conductivity and tensile strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a resin molded article for automotive exterior, comprising the polymer resin blend composition; and (2) manufacturing the resin molded article, comprising forming the first polymer resin and the second polymer resin by injection molding, compression molding, extrusion molding, extrusion compression molding, low pressure injection molding, gas injection molding or foam extrusion.
