Blowing agents - Expancel® Microspheres

When it comes to blowing agents, a controlled foam structure makes your production process go a lot smoother

Not only do Expancel® microspheres expand up to 60 times in volume, they also provide:

  • Highly controlled foaming
  • Closed, uniform cell structure
  • Guards against water penetration
  • Create internal pressure to combat shrinkage

Expancel® microspheres (Expancel® DU, WU, MB, SL , and FG) are the perfect choice as your sole blowing agent or combined with other forms.

Applications

  • Inks and pigments Using Expancel® microspheres in printing ink lets you create your desired surface effect on textiles, wallpapers, polyester film and more.
  • Polymer processing In thermoplastic processing, Expancel® microspheres' uniform, closed cell structure results in a stable, controlled foaming process and is a phenomenal blowing agent on its own or combined with a chemical blowing agent.
  • Food packaging The high compressibility of Expancel® microspheres ensures resilient seals for food packaging, without shrinkage or water absorption.
