Title:
HOLLOW STRUCTURE FOR FUEL
Document Type and Number:
WIPO Patent Application WO/2022/219989
Kind Code:
A1
Abstract:
Provided is a hollow structure for fuel, which is obtained using a fluororesin-containing electrically conductive layer, which exhibits excellent fuel barrier properties and low temperature impact resistance, and which exhibits excellent interlayer adhesive properties. This hollow structure for fuel includes a polyamide resin layer (A), a polyamide resin layer (B), a polyamide resin layer (C) and an electrically conductive layer (D) in the stated order from the outside. The polyamide resin layer (A) includes a polyamide resin (a). The polyamide resin layer (B) includes: a polyolefin; a polyamide resin (b1) that contains a constituent unit derived from meta-xylylenediamine and a constituent unit derived from an aliphatic dicarboxylic acid having 4-8 carbon atoms; and a polyamide resin (b2) that contains a constituent unit derived from xylylenediamine and a constituent unit derived from an aliphatic dicarboxylic acid having 9-12 carbon atoms. The polyamide resin layer (C) includes a polyamide resin (c). The electrically conductive layer (D) includes a fluororesin and an electrically conductive substance.
