    Engineering Plastics and Polyurethane Systems for engine, powertrain and chassis components

      When it comes to the development of challenging components and materials for powertrain and chassis, BASF has been a globally reliable and accepted partner for the automotive industry for decades. The use of engineering plastics, polyurethane systems and additives leads to advantages like weight reduction, functional integration, improved NVH-performance (NVH=noise, vibration, harshness) and cost savings.

      Engineering Plastics and Polyurethanes

      Engineering plastics such as Ultramid®, Ultradur® and Ultraform® as well as polyurethane systems like Elastoflex® and Elastofoam® are particularly suitable for components around the engine and along the chassis: With these materials, components along the entire charge-air duct can be designed, but also cylinder head covers, oil pans, engine mounts, transmission and front end carriers, engine covers, different chassis parts as well as components in the cooling circuit and within the fuel system. BASF plastics contribute significantly to fulfilling the diverse and increasing demands of lightweight construction, functional integration, acoustics and safety.

      The BASF polyamide Ultramid® is particularly suited for components in the engine compartment and in the chassis as it meets further demands of the automotive industry: global specification of uniform materials from local production, tailor-made grades for different temperatures, pressures and loadings, a constantly high product quality as well as technical support for part simulation, application development and realistic parts testing.


    Powertrain: Tailor-made polyamide portfolio for the charge air duct in modern combustion engines

        • Ultramid® grades for various demands on pressure and resistance up to 220°C
        • Selected polyamides available with globally consistent specifications, locally manufactured

        The reductions in fuel consumption and emissions which are prescribed by law in many countries are forcing the automotive industry to act. Besides developing alternative drives, the optimization of traditional combustion engines continues to play a key role. Downsizing results in higher pressures and temperatures, especially in components that carry air behind the turbocharger. BASF is responding to this development in engine designs with a consistent portfolio of PA6 and PA66 grades that meet the higher demands on the materials, their mechanical properties and temperature resistance. Depending on the base polymer and stabilization system, the materials are resistant to heat aging up to 220°C and show excellent burst pressure and weld strength. This means the part developer can be provided with the optimum material for each of the different components in the charge-air duct that offers the best value for money. Selected grades are based on global specifications: They are supplied worldwide from local manufacturing facilities, with uniform material properties and a consistently high level of quality.

        Ultramid® Endure has already been successfully used in several automobiles

        Our versatile PU systems for powertrain parts

        With their versatile properties, our PU systems can make powertrain parts safer, lighter and more robust. BASF polyurethanes can be adjusted to many different densities, they can be flexible or stiff, they resist hot and cold temperatures as well as many aggressive media.

        World's first top mount with polyurethane bearing and polyamide housing

        • BASF combines plastic specialties Cellasto® and Ultramid® for the first time
        • Globally available top mount is 25 percent lighter than aluminum die-cast version with rubber

        BASF is now expanding its expertise in top mounts to enable car manufacturers an optimum combination of weight savings, pleasant acoustics and vibration damping. The unique NVH (noise, vibration, harshness) solution is made possible by combining two of BASF's plastic specialties: the micro-cellular polyurethane elastomer Cellasto® and the highly glass-fiber reinforced polyamide Ultramid® A3WG10 CR. The top mount with the Cellasto® element and the Ultramid® housing is around 25 percent lighter than conventional aluminum die-cast versions with rubber. It was developed and optimized for serial production using BASF's simulation tool Ultrasim®.
