Fuel Storage

At the Heart of Fuel Storage

Look to DuPont for advanced solutions under development to meet the most demanding needs for low permeation barrier materials. For example, meet the low permeation challenges with laminar barrier technology – molded into fuel tanks with an integral barrier layer of overlapping Selar® barrier resin platelets.  This cost-effective process can reduce permeation up to 98%.

Virtually no other company can supply the range of materials that DuPont offers.  For example, in the fuel inlet area, you can specify a filler door and pocket of durable Minlon® mineral reinforced nylon and a filler cap of tough anti-static Zytel® nylon and Delrin® acetal. For low-permeable fuel hose and tubing, DuPont offers Teflon® and Tefzel® fluoropolymers that are used in a variety of different multi-layer constructions.  Materials and expertise combine to make DuPont your innovation partner for fuel storage.

Capless fuel filler locks out wrong nozzles using parts molded from Zytel® HTN

Ingenious capless filler design molded from Zytel® HTN eliminates need to remove and replace fuel cap, reduces evaporative emissions, automatically seals shut when nozzle is withdrawn, and avoids paint scratches from dangling caps.
