Corrosion Resistance

Fuel tanks are regularly exposed to the corrosive action of their contents (fuel) and of other elements such as road chemicals, salt, mud, gravels, etc. If nothing is done to protect them from a long-term exposure to corrosion, they can become weaker and wither after some time. At this stage the risk for a defective fuel tank to leak, burn and explode is particularly high and therefore has to be controlled.

Plastic fuel tanks are particularly well protected against corrosion and do not need any special coatings on their structure for that. In fact, the material they are made of, high-density polyethylene (HDPE), is highly resistant to corrosion and makes it possible to have a structure which is inert to the corrosive environments inside and outside the tank. In addition, HDPE can also help dissipate electrostatic charge and prevent igniting fuel.
