W. Muller USA Inc., Agawam, Mass., has developed a special continuous-extrusion head design for blow molded barrier fuel tanks made of a newly formulated Ixef polyarylamide (MXD6 nylon) from Solvay Advanced Polymers, Alpharetta, Ga. The modified material is aimed at small fuel tanks for watercraft, lawnmowers, and motorcycles, as well as automotive filler tubes and other fuel-system components. The head is designed to put a very thin barrier layer on the inside of the tank. Newly established processing parameters reportedly ensure optimum cooling and adhesion. The result is said to be cost-effective two- and three-layer structures with barrier performance equivalent to a five-layer EVOH construction. They are said to meet the EPA’s Partial Zero Emission Vehicle (PZEV) standard and California Air Resource Board (CARB) regulations.
