An Innovative Multi-Layer Plastic Construction for PZEV Fuel Systems 2003-01-3075

An innovative multi-layer plastic fuel tank construction has been developed. This new structure meets the most stringent evaporative emissions requirements of PZEV vehicles, while still offering the advantages of plastic fuel tanks (crash worthiness, design flexibility, low weight, excellent chemical and corrosion resistance). The construction incorporates a new polyamide/HDPE alloy barrier material as the inner layer, processes easily on conventional 6-layer blow moulding equipment, and reduces evaporative emissions, especially at the pinch-off line. Further, it complies with the LEV 2 evaporative durability requirement of 15 years or 150,000 miles.
