Dana Corp. to provide new multi-layer fuel lines - North America - Nitta Moore Co. Ltd - Brief Article

Automotive Industries, Jan, 2004

Dana Corp. will begin producing new, multi-layer fuel lines for various applications in Europe, North America and South America.

The announcement comes after Dana signed a five-year licensing agreement with Nitta Moore Co. Ltd. of Japan to extrude polybuthylene naphthalate (PBN) multilayer tubing for the automotive fuel market.

PBN can be extruded in small and large sizes with conductive, non-conductive, and corrugated configurations. This innovative product has potential application for fuel feed, fuel return, and fuel vapor lines, as well as tank filler necks. When compared to older fluoropolymer multi-layer tubing, improvements are evident in low permeation, electric static discharge (ESD), weight and cost.

The new multi-layer PBN tubing is made up of five different layers: a PBN middle layer, two adhesive layers and Nylon-12 internal and external layers.
