NAFILite and NAFILean
Hemp-Fiber-Based PP for Reduced CO2 Emissions
Weight reduction is crucial to equipment suppliers and automakers who are seeking to curb emissions. A 10 kg reduction in vehicle weight is enough to cut CO2 emissions by 1 g/km. Faurecia designed and developed its hemp-fiber-based NAFILean and NAFILite materials to help achieve these goals. Hemp is an eco-friendly, non-food crop that requires no pesticides, fertilizers or irrigation.
The abbreviation NAFI stands for natural fiber for injection. According to the manufacturer, NAFILean is the automotive interior market’s only injected material with natural fibers. NAFILean integrates a natural, hemp-based fiber with polypropylene and allows for complex shapes and architectures along with weight reduction. This mixture produces injected parts with a substantial 20 to 25 % weight savings in comparison with standard plastics and contributes to make the car more fuel efficient. It also reduces the overall environmental impact by 20 to 25 % through the components’ lifecycle. It has been developed to introduce green content into high-performance material for instrument panels, door panels and center consoles. NAFILean can be used in traditional injection machines and stands as a unique market solution from Faurecia.
NAFILite is a combination of NAFILean material and an injection (foaming) process used to expand the material through mold-opening technology. Its stiff, microcellular (bubble) structure ensures much-improved performance and resistance. This requires less injected material, which leads to significant weight savings. NAFILite offers a 15 % weight saving vs a market reference material and up to 30 % weight saving vs the traditionally used materials for such parts. Made of renewable natural fibers and of polypropylene, it also gives an environmental impact reduction of up to 30 %.
