      Our versatile PU systems for the automotive interior

      With their versatile properties and unlimited application possibilities, our PU systems can make the automotive interior safer, more comfortable and more beautiful. BASF polyurethanes can be adjusted to many different densities, they can be soft or hard, flexible or stiff, they resist hot and cold temperatures as well as many aggressive media.

    Elastoflex® W – Flexible Foam System

      The flexible foam system Elastoflex® W decisively contributes to car comfort. Besides its well-known value for seating applications, guaranteeing comfortable feeling in the car’s seat even at long and dynamic driving, it also contributes to the sound impression in the driver’s cabin. In comparison to other acoustic solutions, Elastoflex® W performs not only as sound absorber, reducing reverberation effects, but also dampens sound from outside the car by visco-elastic energy dissipation. Current systems follow the latest demands on air quality in the driver’s room controlled by external institutes according to e.g. VDA278 or chamber tests. Especially designed foams resist also high temperatures and media contact. These foams are widely used in direct contact to the engine as NVH (noise, vibration, harshness) and heat management solution.

    Elastofoam® I – Flexible Integral Skin Foam

      Although having an open-cell foam core structure, Elastofoam® I has been developed to form an integral skin as decorative and protecting surface in a one-shot process. Using water as a chemical blowing agent or physical blowing agents, Elastofoam® I reproduces the texture of the mold surface perfectly. Mostly in combination with an appropriate coating these flexible integral systems provide a soft, pleasant touch combined with a UV-, scratch- and abrasion resistant surface of smooth haptic.

    Elastoskin® I – Elastomers for Skins

      PU is known as the material of choice for high-quality looks as well as fine tactile, haptic skin surfaces. Combined with in-mold coating (IMC) Elastoskin® I provides surface parts with very fine grain textures resistant to UV light, scratch or impact as well as to cleaning agents, sun cream or sweat - even for multi-coloured parts. In comparison to competing materials, Elastoskin® I contains no plasticizers known to cause problems with migration, interaction with back-foaming, discolorations or emissions. Additionally, the respectively low mold temperature of 75°C and the absence of any chlorine, known to be problematic in waste, contribute to a sustainable energy consumption in production and waste combustion. The mechanical properties of Elastoskin® I are not influenced by either very low or high temperatures.

    Elastollan® – Thermoplastic Polyurethane (TPU)

      Where conventional materials reach their limits, Elastollan® in vehicles can make all the difference. It is noted for its excellent haptics and mechanics, as well as its superior long-term durability and resistance to weathering. It gives freedom for a lot of design possibilities. Its strength lies in its versatility: the properties of Elastollan® can be readjusted and recombined time and again – depending on the application and the specific requirements of the component. For example, it shows high temperature as well as good media resistance and has superior dynamic properties. Its damping behavior is excellent as is its resistance against abrasion, scratch and wear.

    Elastocoat® C – Clearcoat for Decorative Surfaces

      Surface parts from wood are becoming more and more popular in car interiors. They have to be protected against sun and degradation. Elastocoat® C cold-cast systems and coatings offer a transparent, lightfast, scratch-resistant and also self-healing surface of particular flair.

    Elastoflex® E – Semi-Rigid Foam System

      Although invisible, Elastoflex® E semi-rigid foams contribute extensively to the valuable appearance in car interiors, since the foam is behind most skin surfaces and causes a pleasant, soft and elastic touch. Though it needs to fill even smallest gaps between carrier and skin, e.g. in instrument and door panels as well as armrests and curbs, it spreads homogeneously at very robust processing.  Elastoflex® E systems offer a high flowability at fast demolding times suitable for all skin types, individually designed for all special OEM requirements. Although applications are diverse, it is BASF’s goal to provide one system for many parts in order to reduce customers’ complexity and cost structure.

    Elastoflex® E – Thermoformable Foam with ISO 116 Adhesives

      PU systems are in many cases injected into a cavity as a reactive liquid mixture and foam or cure directly in desired shape. However, PU systems can also be foamed and cured in blocs batch-wise or continuously. Elastoflex® E 3943 is foamed as free-rise blocs and offers a very open-cell foam at an extreme low density of 12-35g/l. Since these foam types are thermoformable, they can be shaped in a common hot press and bonded to diverse surface materials in a continuous process using the specially designed adhesive series ISO 116. Components benefit from the very light material with excellent sound absorption also at low part thicknesses suitable for formed 3D parts with deep contours at high stiffness.

    Elastoflex® E and Elastolit® D – Semi-Structural Foams

      The low-density Elastoflex® E and Elastolit® D semi-structural foams are designed for producing very light and stiff composite as well as sandwich structures for various interior and exterior applications such as load floors, interior lining parts, roof modules and engine hoods. Reinforced with long-glass fibers in state-of-the-art composite processes, thin-walled parts with good mechanical properties yet light in weight can be realized. Such composite substrates can be combined with various surface materials like textiles or thermoplastic films, either by back-foaming or glueing.

      Possible applications for our PU systems for the automotive interior

      Whatever your specific needs for your interior application: BASF connects new material developments and services in order to create system solutions which give your interior application the distinctive advantage.

      In-mold-coating (IMC) spray skin with Elastoskin®

      Travel light and comfortable with superior quality for high-class surfaces: The Elastoskin® spray skin for interior applications sets new standards. It is a polyurethane spray system for high-quality, soft-touch surfaces for instrument panels, door modules and center consoles – in the car and commercial vehicle segments.

      Plastic Additives

      Light stability – a key requirement for plastics in automotive applications

      Exposure to sunlight, especially at high ambient temperatures, results in loss of mechanical performance and discoloration. BASF provides a wide range of light stabilizers and UV-Absorbers used in cockpits. BASF’s thermal stabilizers protect plastics from oxidation caused by exposure to heat and prevent loss of mechanical properties and esthetics.

      Meeting new regulations

      Regulatory considerations are increasing the demand for low-emission, low-odor substances. BASF offers a wide range of light stabilizers and thermal stabilizers to cope with the tough demands of plastic interiors.

      Durability and resale value – preserved and perceived quality

      BASF’s Irgasurf® SR anti-scratch additive improves the scratch and mar resistance of interior automobile parts made of PP and TPO, such as instrument and door panels as well as consoles. BASF’s Irgastat® P permanent antistatic and anti-dust agents prevent plastic parts from attracting dust. Light-colored, permanently clean parts like sun visors and overhead compartments contribute to increased perception of comfort and appearance. BASF’s nucleating agent Irgastab® NA helps to reduce cycle time and increase output by supporting thin wall design and weight reduction.
