Expancel® microspheres

Blowing agent and lightweight filler in one

Find

A world of possibilities.

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
