Q&A from the Experts

  • How does polyurethane foam help improve fuel efficiency?

    Polyurethane helps reduce vehicle weight without sacrificing strength and durability. BASF's innovative polyurethane composite systems are being used to reduce the weight of load floors in a variety of vehicle types and platforms. From incredibly thin honeycomb cores encapsulated in LFI (long-glass fiber injection) polyurethane, to rigid polyurethane foam cores sandwiched between hardboard skins, BASF offers an affordable solution for every load floor application.


    Far stiffer than traditional polypropylene floors and far lighter than hardboard floors, load floors made with polyurethane composites take mass out of your vehicles while improving strength.


    In addition, the design flexibility offered by polyurethane helps enhance aerodynamics and reduce the weight of mudguards, bumpers, door sills, spoilers, hoods, wing mirror housings and roof modules.

  • What is Cellasto®?

    This microcellular polyurethane elastomer is used to create auxiliary springs, support bearings and chassis components. Its excellent characteristics ensure a reduction in NVH and a clear increase in comfort and road dynamics. BASF is the world leader in microcellular polyurethane components.

  • How do polyurethane-based composite parts compare with vinyl esters or polyesters?

    BASF urethane composites add strength while reducing weight in all kinds of RV and ATV components. This includes better impact resistance, similar HDT (Heat Deflection Temperature) and 25% less weight than parts made of vinyl esters or polyesters. BASF composites also offer molding efficiencies, reduce emissions during molding and eliminate VOCs.

  • What are the progressive deflection characteristics of Cellasto®?

    The density of these moldings range from 350 kg/m³ to 650 kg/m³ depending on the mass of material used. Their cell volume amounts to 63% to 50% of the molding volume. The cell diameter amounts to tenths of a millimeter and the cells can be open or closed depending on the density. Compression loads first compress the cell volume and later the material itself. It therefore becomes harder as compression increases.

  • What is the lateral expansion and volume compressibility of Cellasto®?

    Compact elastomers such as rubber, for instance, respond to compression with high lateral expansion. Cellular polyurethane elastomers, however, only create very low lateral expansion.

  • Do I need to take creep into consideration when using Cellasto®?

    When dimensioning Cellasto® mouldings the so-called creep - compression increasing over time under constant load - must be taken into consideration.
