Bayer MaterialScience’s new material is lighter than water
Updated 2005 Ford GT. To create this, Bayer MaterialScience used Bayflex180 RRIM system for its strength, heat performance and ability to mold complex shapes.

MAASTRICHT, THE NETHERLANDS: Demand for lightweight construction systems in the automotive industry is now at an all-time high, with the aim being to cut fuel consumption, costs and CO2 emissions. According to VCD Verkehrsclub Deutschland, reducing the weight of a vehicle by 100 kilogramme lowers fuel consumption by 0.5 litre over a distance of 100 kilometre and cuts carbon dioxide emissions by 1.2 kilogramme over the same distance.

Lightweight structures are now more important than ever given the trend toward future-oriented drive technologies such as electric mobility. Moving a step ahead, Bayer will present its Bayflex RIM Light Weight polyurethane system, a material that can be used for further reducing weight of finished components by up to 30 per cent. With a density of 0.9 kilogramme per litre, this material is even lighter than water. “This solution owes its lightweight design to the high-grade Bayflex polyurethane system in tandem with clever combination of fillers that replace the usual mineral fibre. The mechanical properties remain intact,” explained Dr Birgit Meyer zu Berstenhorst, responsible for developing the material.

The material enables a considerable reduction in fuel consumption and CO2 emissions and with certain vehicle models, also improves driving dynamics. In electric cars, this better compensates for the still considerable weight of the battery and helps extend the vehicle’s range. This compact material is processed using tried-and-tested RRIM (Reinforced Reaction Injection Molding) technology. In addition to car components, Bayflex RIM Light Weight can be used for applications in trucks, buses, trains, aircraft, ships and in leisure and furniture sector.
