Abstract:
Provided is a component used in a fuel feed apparatus ( 500 ), containing: a conductive polyamide layer ( 25 ) formed of a conductive polyamide resin composition, in which the conductive polyamide resin composition contains: a polyamide resin, a conductive carbon black, an ethylene-α-olefin copolymer, and a conductive polyethylene resin, and satisfies the following characteristics (a) and (b): (a) initial volume resistivity of a flat plate obtained by injection forming is 1×10 5  Ω·cm or less, and volume resistivity after exposing the flat plate to CM15 fuel for 168 hours is 1×10 7  Ω·cm or less, and (b) charpy impact strength at −40° C. of a test piece obtained by injection forming is 2.0 KJ/m 2  or greater.

Claim (Index 1):
A component used in a fuel feed apparatus ( 500 ) that feeds fuel to a fuel tank (FT), the component comprising:\n a conductive polyamide layer ( 25 ) that is configured to be in contact with fuel or fuel vapor in a use state, and is formed of a conductive polyamide resin composition, wherein the conductive polyamide resin composition comprises:\n (A) 84 to 40% by weight of a polyamide resin, \n (B) 5 to 30% by weight of a conductive carbon black, \n (C) 3 to 30% by weight of an ethylene-\u03b1-olefin copolymer having a reactive functional group capable of reacting with a terminal group and/or an amide group in a main chain of the polyamide resin, and \n (D) 1 to 20% by weight of a conductive polyethylene resin, and \n wherein the conductive polyamide resin composition satisfies the following characteristics (a) and (b):\n (a) initial volume resistivity of a flat plate (100 mm\u00d7100 mm\u00d72 mm (thickness)) obtained by injection forming the conductive polyamide resin composition is 1\u00d710 5  \u03a9\u00b7cm or less, and volume resistivity after exposing the flat plate to CM15 fuel for 168 hours is 1\u00d710 7  \u03a9\u00b7cm or less, and \n (b) charpy impact strength at \u221240\u00b0 C. of a test piece obtained by injection forming the conductive polyamide resin composition is 2.0 KJ/m 2  or greater.
