Tires account for 20% to 30% of vehicles\u2019 fuel consumption \u2013 mainly because of their rolling resistance. They are high-tech products that require innovative \u201cingredients\u201d. Innovative high-performance rubbers enable tire makers to create advanced tires with less rolling resistance and help to save 5 to 7% of fuel consumption. All this can be achieved without compromising on safety.<\/p>\n
High-performance rubber for green tires<\/p>\n
Environmentally friendly quality tires \u2013 also known as \u201cgreen tires\u201d \u2013 that contain high-performance rubbers from LANXESS – offer numerous advantages on the road, such as efficiency and environmental sustainability, good braking performance and maximum safety, higher mileage and longer service life, as well as low noise pollution.<\/p>\n
For the production of green tires for green mobility, LANXESS already markets rubber raw materials that enable fuel consumption to be substantially reduced. Examples include new, modified grades of solution styrene-butadiene rubber (SSBR) and refined grades of neodymium-polybutadiene rubber (Nd-PBR), which effectively reduce the high internal friction of tire components. Initial laboratory and practical tests indicate that tires made of these materials not only have good rolling resistance, they also give outstanding grip. On top of that, they have a very long service life.<\/p>\n
According to Professor Horst Wildemann from the Technical University of Munich, reducing rolling resistance by one kilogram per metric ton lowers the fuel consumption of a vehicle by 0.08 liter per 100 kilometers. At the same time, CO2<\/sub> emissions are cut by 200 grams per kilometers.<\/p>\n The tire industry and its suppliers have been involved in the collective efforts to reduce CO2<\/sub> emissions attributable to road traffic. LANXESS has always been a pioneer in the development of tires, which constitute the company\u2019s most important customer group, accounting for around 60% of its overall sales. Here, custom-formulated high-performance rubbers such as neodymium-butadiene rubber (Nd-BR) and solution styrene-butadiene rubber (SSBR) have developed into the most dynamic market segment with annual growth rates of around 10%.<\/p>\n The most representative application of Nd-BR and SSBR is their use in the Buna \u00ae CB tires and Buna\u00ae VSL tires respectively. Produced by the Performance Butadiene Rubbers business unit (PBR) of LANXESS, the products of these two series aim at improving abrasion resistance, crack resistance and lowering heat build-up under dynamic load. Yet, what\u2019s most worth noting is their unparalleled contribution to green mobility.<\/p>\n Buna\u00ae CB tires and Buna\u00ae VSL tires bring enormous benefits by keeping tire pressure on the optimum level. An optimal tire pressure is the key to gaining low rolling resistance, thereby effectively improving fuel efficiency and reducing CO2<\/sub> emissions.<\/p>\n Rolling resistance accounts for around 30% of a vehicle\u2019s fuel consumption. It results from the deformation of the tire to create a sufficient contact area on the road. This is what essentially transmits the propulsion power. Every time the tire turns and deflects, it absorbs energy, converts it into heat and then discharges it into the environment. Thus, the firmer the tire tread clings to the road surface and the lesser the air in the tire, the greater the energy loss through friction and deformation.<\/p>\n High performance rubber grades like Buna\u00ae CB and Buna\u00ae VSL share an outstanding resilience that reduces the rolling resistance of tires without negative effects on safety.<\/p>\n LANXESS also ranks among the world\u2019s top manufacturers of high-performance halo-butyl rubbers. Chlorobutyl\u00ae and Bromobutyl\u00ae, principally used in the production of inner liners and inner tubes, are the two main brands. Keeping the interior pressure at the optimum level, inner liners made of butyl rubber provide the tire with high impermeability to air so that the rolling resistance is lowered. As a result, the fuel efficiency is effectively improved and the CO2<\/sub> emissions reduced. When used in tread compounds, they provide softer tires with better grip and comfort as well as improved wet traction, which enhance the safety of tires.<\/p>\n","protected":false},"excerpt":{"rendered":" Tires account for 20% to 30% of vehicles\u2019 fuel consumption \u2013 mainly because of their rolling resistance.
