Why go with something like glass microspheres when you can get much lower densities with us? Since today’s consumer goods need to be amazingly light, while being the right size proportions, manufacturers face several challenges. Expancel as a lightweight filler will add volume without significantly adding weight, many times with a positive effect on the final product properties. It allows you to substitute heavier substances with small portions of Expancel expanded microspheres and achieve better overall results. This means making true quality, lightweight products without sacrificing volume. And saving big on raw material costs in the process.

Our DE (dry, expanded) and WE (wet, expanded) variants have densities as low as 25kg/m³ depending on the product.
