When it comes to a blowing agent, 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 promise highly controlled foaming and a closed, uniform cell structure when used as a blowing agent. In some applications, this guards better against water penetration. In others, it lets you create internal pressure to combat shrinkage.
Compared to chemical blowing agents Expancel Microspheres’ fine, uniform cells achieves a more controlled result on foamed end products. However, if your application calls for a ‘best of both worlds’ effect, Expancel can be mixed with chemical or physical blowing agents.
It’s what makes Expancel Microspheres (Expancel DU, WU, MB, SL and FG) the perfect choice as your sole blowing agent or combined with other forms.
Our microspheres, decades in the making, are thermoplastic particles with shells that encapsulates gas. This will make your product not just cost effective and light but also add numerous other benefits.
They expand at temperatures ranging from 80°C - 235°C (185°F - 455°F) for a range of advantages and a host of applications.
