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.
