Detroit, Michigan -- As automotive companies continue to look for ways to reduce vehicle weight, Canada's Woodbridge Group is widening its range of polyurethane materials to help them meet their targets.
"We are seeing more vehicle manufacturers and seat assemblers looking more closely to lightweighting materials, and the cumulative effect of mass compounding, to reduce passenger vehicle weight," said Martin Mazza, senior vice president of marketing and global sales with Woodbridge.
Estimates show a vehicle's fuel efficiency increases 6-8 percent for every 10 percent drop in weight, Woddbridge's statement noted.
"Woodbridge continues to evolve GreenLite low-mass automotive seating and headliner solutions," offering "optimised performance from lighter, more cost-effective components," Mazza added.
ComforTech performance urethanes offer automotive seating the ideal balance between comfort and durability, according to the group, while GreenLite low-mass seat-cushioning now delivers greater firmness across a wider density range, for each specific area within the seat cushion and back.
As Woodbridge puts it, "advanced ComfortZone technology offers new levels of automotive seating comfort, at a lower cost while providing up to 30 percent weight reduction."
Another advance, StructureLite seat frames, using polyurethane or expanded polypropylene, is used in seat cushions, backs and bolsters.
GreenLite has enabled even greater potential for mass reduction, offering advantages over conventional wire frames: improved occupant safety through integrated anti-submarine ramps; better trim fit and appearance; safer trim attachment; system cost savings; and up to 35 percent weight reduction.
Woodbridge's GreenLite low-mass technology has further enhanced two automotive headliner innovations. StrataLiner NET composite boards deliver improved acoustical performance, and when package space is at a premium, StrataLiner NXT boards provide cross-sections as thin as 2.5 mm. System advantages over competing polypropylene composites include: thinner cross-sections; superior design flexibility; enhanced surface quality; improved acoustics; better side-curtain air-bag compatibility; system cost savings; and up to 40 percent weight reduction.
The Woodbridge Group also offers BioFoam products, manufactured with renewable polyols, to offer automakers less dependence on non-renewable fossil fuels and a smaller environmental footprint.
