New Xenoy polyester alloys from GE Plastics, Pittsfi eld, Mass., are claimed to meet new and stricter fuelpermeation regulations for small-engine fuel tanks. Xenoy X6800BM polyester alloy for blow molding and Xenoy 6620-GT, a PC/PBT for injection molding, can be used for monolayer tanks that meet current and future California Air Resources Board (CARB) and U.S. EPA standards, according to GE. Applications include small off-road engine (SORE) fuel tanks for lawn mowers, snow blowers, personal recreational vehicles, and generators. The materials comply with the current 20072008 CARB standard which limits fuel emission to 2.5g/m2/day, but also comply with the tighter 20112012 limit of 1.5 g/m2/day at a typical tank thickness of 3 mm. Xenoy tanks are said to be less costly than multilayer coextrusion blow molding or secondary fl uorination of monolayer HDPE tanks. Other properties of the new Xenoy materials are high- and low-temperature ductility, uv stability, and suitability for hot-plate and vibration welding. Commercial applications are expected in lawn and garden later this year. Tel: (413) 448-5700 . www.geplastics.com
