Resin-made fuel inlet pipe, and method for producing same

摘要

A resin-made fuel inlet pipe that has a light weight, excellent impact resistance, and causes no fuel leakage includes at least one resin layer comprising a resin composition containing (A) a high-density polyethylene (HDPE) or a linear short-chain branched polyethylene; (B) a polyethylene polymerized with a metallocene-based catalyst; and (C) a carbon black. A weight mixing ratio ((A)/(B)) is in a range of from 10/90 to 90/10; a content of component (C) is in a range of from 0.1 to 5 parts by weight with respect to 100 parts by weight of a total of components (A) and (B); a tissue (Y) comprising component (B) is inserted between linear crystalline tissues (X) comprising component (A) to expand an interval between the tissues (X); and component (C) is dispersed in the tissue (Y).

1. A resin-made fuel inlet pipe comprising at least one resin layer, the resin layer comprising a resin composition containing the following components (A) to (C):
(A) a high-density polyethylene (HDPE) or a linear short-chain branched polyethylene; (B) a polyethylene polymerized with a metallocene-based catalyst; and (C) a carbon black, wherein: a weight mixing ratio ((A)/(B)) between the component (A) and the component (B) falls within a range of from 10/90 to 90/10; a content of the component (C) falls within a range of from 0.1 to 5 parts by weight with respect to 100 parts by weight of a total of the component (A) and the component (B); a tissue (Y) comprising the component (B) is inserted between linear crystalline tissues (X) comprising the component (A) to expand an interval between the tissues (X); and the component (C) is dispersed in the tissue (Y).
