Abstract
A blow moulded automobile fuel tank having a wall defining a fuel chamber wherein the minimum wall thickness of the wall is from 2.4 mm to less than 3 mm, the tank being composed of a high density polyethylene having a density of from 0.945 to 0.955 g/cm3, a high load melt index of from 5 to 9.5 g/10 min, the high density polyethylene optionally having a carbon black content of up to 0.5 wt %, and the fuel tank having a fire resistance and an impact resistance both complying with the respective standards defined in ECE 34, ANNEX 5.
Claims6
An impact and fire resistant blow molded automobile fuel tank having a wall defining a fuel chamber which wall varies in thickness wherein the minimum wall in one or more portions of the wall is from 2.4 mm to less than 3 mm, the tank being composed of a high density polyethylene having a density of from 0.945 to 0.955 g/cm3 and a high load melt index of from 5 to 9.5 g/10 min, the high density polyethylene optionally having a carbon black content of up to 0.5 wt %, and the fuel tank meets fire resistance and impact resistance standards in ECE 34, Annex 5, such that it resists an open/semi open fire for two minutes and, when filled with ethylene glycol and subjected to impact at −40° C., does not split open.
