Boud Microspheres are Boud Mineral’s range of lightweight fillers, this includes Expancel® DET Microspheres and Microsphere blends we produce at our main site in Lincolnshire, United Kingdom.

Expancel® DET Microspheres, and the blends we make with them, possess unique properties that offer surprising possibilities. When you need to reduce weight, improve quality, create bespoke finishes, cut manufacturing or transportation costs, our microspheres deliver.

Our microspheres are remarkably different from ceramic or glass microspheres. They are elastic, flexible and resilient. This means they can withstand higher mechanical stresses, during pumping, hard mechanical mixing or spraying, without being destroyed and losing their volume. The extremely low density of our microspheres means they can be added in much lower quantities than ceramic or glass microspheres to give the same volume.

In our Boud Microspheres website you can find out more about the benefits of adding Expancel® DET, or our microsphere blends, to your products, how to use them, your product and packaging choices, and how we can help you achieve your goals.
