Possible to expand to extremely low densities. Our powerful dry, unexpanded microspheres add countless advantages to your production process and its outcome. Not only will Expancel DU let you achieve desired surface aesthetics in artificial leather and wallpaper, it'll also help your produce plastics that are light and smooth. On top of that Expancel DU can stand high shear forces and pressure during processing.

The microspheres in Expancel DU expand with heat and are preferably used in systems where no water can be added. Expandable at temperatures between 80°C - 235°C (176°F - 455°F), our microspheres will unleash a range of essential benefits for product developers in different industries.

Expancel DU is bursting with benefits
