Expancel® Microspheres is a lightweight filler and blowing agent all in one. Its high performance opens a world of possibilities

It is a simple concept – a small thermoplastic microsphere encapsulating a gas. Add heat and the gas expands while the shell softens giving a dramatic increase in volume. This will help you:

  • Cut manufacturing costs
  • Reduce weight
  • Improve yields
  • Minimize the use of resin
  • Create attractive textures and more

Expancel® FG for food packaging offers high compressibility, no shrinkage, no moisture absorption and is approved by regulatory authorities.

Expancel® WE and Expancel® DE for elastomeric cool-roof coatings give superior reflectance and elasticity and reduce cost and weight.

Expancel® DU and Expancel®​ DE are used by the automotive industry to reduce weight, dampen sound and improve sealing.
