Atofina has worked with automotive industrial blow molder TI Automotive to develop a novel multilayer structure specifically for fuel tanks. The new six-layer structure complies with California’s stringent “partial zero emissions vehicle” (PZEV) regulations. TI has utilized this structure to develop and patent the Permablock AS6 plastic fuel tank, the first of its kind to comply with the PZEV regulastions.

The six-layer structure is comprised of Finathene high-density polyethylene, a recycled layer, resin tie layers and Soarnol ethylene vinyl alcohol copolymer (EVOH) and Orgalloy polyamide alloy. Finathene grade MS B HDPE is used as the outer layer in this structure to provide processability as well as impact resistance at low temperatures.

Two barrier layers, an intermediate layer of EVOH and a core layer of Orgalloy polyamide alloy provide excellent overall barrier properties. Additionally, the grade of Orgalloy used, FT 104, is well suited to conventional extrusion blow molding using standard production tools. Orgalloy FT 104 also has good chemical and thermal stability, making it suitable for continuous contact with fuel
