Fuel tube

摘要

A fuel tube (12,12B) having an ethylene-vinyl alcohol copolymer (EVOH) layer (14) formed of an EVOH-based extruded EVOH material, and a modified HDPE layer (16,16B) formed of an extruded HDPE material which is based on modified high density polyethylene (modified HDPE) or is based on a polymer alloy containing mainly modified HDPE. The modified HDPE is a dicarboxylic acid-modified material having a melt mass flow rate value (190 DEG C: JIS K 7210) of about 0.2 to 10.0g/10min. The interlayer adherability between the EVOH layer (14) and the modified HDPE layer (16,16B) is maintained while maintaining the anti-fuel permeability and the flexibility of the fuel tube (12).
