Resiliency and shock absorption

Compressibility by Expancel Microspheres

Expancel Microspheres

If you squeeze an expanded Expancel Microsphere, it compresses. Let it go and it recovers. The high resiliency of our microspheres means they can withstand several cycles of loading/unloading without breaking. This makes them highly suitable for use in shock absorbent materials.

The compressibility effect can be used in products such as:

  • Concrete: Expancel absorbs the pressures of freezing water creating a good frost resistance.
  • Sealants: Expancel reduces the weight with retained elasticity.
  • Cultured marble: even a very small amount of Expancel improves the thermal shock resistance.
  • Sports protective gear: improved impact absorption and foam recovery give better resistance to multiple impacts.
  • Underbody coatings: the microspheres will pass the spray nozzle without breaking and with maintained volume.

The compressibility and resiliency of our microspheres are unique features that can give your product that little extra. Contact us to find out more about our lightweight filler.
