Microcellular polyurethane elastomer


Cellasto® is a microcellular polyurethane elastomer (MPU) sold as finished product mainly to the automotive industry. In fact, Cellasto is inside every second car manufactured in the world.


Under the Cellasto brand, BASF develops, produces and distributes components from microcellular polyurethane elastomers that enhance driving comfort. Cellasto not only is more robust and durable, it has superior physical properties when it comes to minimizing noise from the engine and isolating vibrations from the chassis, shock absorbers and struts. The microcellular polyurethane foam saves space and weight due to its excellent volume compressibility.



    Low compression set
  • High abrasion resistance
  • Ozone resistance
  • Cadmium-free
  • Very good static and dynamic long-term behaviour
  • High-volume compressibility with minimum lateral expansion
  • Low dynamic hardening and amplitude-selective damping
  • Resistance to oils, greases and other aliphatic hydrocarbons


Learn how Cellasto® helps combat one of automotive engineering’s toughest challenges: effectively reducing noise, vibration and harshness in consumer, commercial and industrial vehicles.
