Unexpanded microspheres act as a blowing agent when mixed in a product and subsequently heated to cause expansion within the matrix. The expandable microspheres can be 6 to 40 micrometers in average diameter and have a density of 900 to 1400 kg/m3.

Here the product must be heated at some point in the process for the unexpanded microspheres to expand.
