ANTISTATIC TUBE OF POLYAMIDE BASE FOR GASOLINE TRANSPORTATION

摘要

PROBLEM TO BE SOLVED: To provide an antistatic tube for gasoline transportation of a polyamide base impermeable to gasoline containing alcohol. SOLUTION: This multilayer tube of a polyamide base has layers (1)-(4) toward the outside from the inside. The inner layer 1 is made of polyamide in which electroconductive carbon black or a polyamide/polyolefine mixture with a matrix of polyamie to make surface resistivity less than 106Ωis dsipersed. The intermediate layer (2) is made of polyamide not containing electroconductively significant quantity of carbon black or a polyamide/ polyolefin mixture with a matrix of polyamide, and the bonding layer (3) and the outer layer (4) are made of polyamide.
