From small microsphere to big idea

It’s a simple concept – a small thermoplastic microsphere encapsulating a gas. Add heat and the gas expands while the shell softens. The result is a dramatic increase in volume and billions of new possibilities. Expancel has dual functionality as both a lightweight filler and a blowing agent. When you need to cut manufacturing costs, reduce weight, create attractive textures, protect against damage or shield against the elements, Expancel Microspheres delivers.

Product description

We offer a variety of chemical compositions to give expansion at different temperatures. A range of particle sizes available  - expanded or unexpanded  - makes it possible to achieve numerous surface effects, including matting, smoothness and roughness. The very low density gives a significant weight reduction even at small dosages of our microspheres.
