Sanoh selected Arkema’s Rilsan® PA11 for innovative partially zero emission vehicle (PZEV) multilayer fuel line

This innovative new multilayer technology exhibits very high barrier properties leading to a significant reduction of the permeation of hydrocarbons, even when the gasoline contains ethanol. Compared to existing multilayer combining polyamide 12 and ETFE, the permeation level is significantly lower as well as the cost.

Thanks to the combination of Arkema’s biobased Rilsan® PA11 with fuel barrier PPS, these new fuel lines including both conductive and non conductive types, comply with stringent Japanese Automotive standards.

Rilsan® PA11 was chosen for its unique chemical resistance (sour gasoline resistance), cold impact resistance, as well as its pressure resistance and durability at high temperature. Global warming and other environmental concerns drive advances in the automotive industry to minimize the environmental impact of today’s cars. Governmental regulations such as Californian Legislation or EURO 5 set restrictive limits for fuel and tailpipe emissions and are tightening towards zero emission levels. In order to comply with this stringent legislation, the fuel system is equipped with barrier materials to minimize the diffusion of the fuel through the fuel system. The combination of Rilsan® PA11 with fuel barrier material PPS leads to a completely new multilayer construct opening its use in partial zero emission vehicles. In addition, the use of renewable source materials and fuels, such as biobased Rilsan® PA11 and biofuels, can significantly reduce greenhouse gas emissions and dependence on fossil fuels. Recently, Rilsan® PA11 Biodiesel grade won a European 2006 Bioplastic Award for its impressive compatibility with Biofuels and other aggressive fuels.

Arkema commercializes its patented multilayer fuel line technology under the brandname Rilperm® and offers a wide range of cost-effective multilayer structures to meet specific application and regional needs. The website at http//www.rilperm.com features a wealth of technical information on Arkema’s multilayer product portfolio for the Automotive industry.

Arkema is committed to sustainable development by developing and marketing products for today’s generations, and not at the expense of tomorrow’s generations. The use of renewable source materials and fuels such as biodiesel and flexfuel combined with the use of biobased Rilsan® PA11 can significantly reduce greenhouse gas emissions.
