Description
A common name for Glass or Ceramic compounds that are physically formed into microscopic spheres. Microballoons, or microspheres, are finely divided, free-flowing particles that have high strength. The soft, white powder is used as low density extender in plastics and adhesives. Microballoons are also used in industry for filtration systems, as containers for radioactive traces, for thermal insulation layers in nonwoven fabrics, and to form a protective layer over liquid surfaces. In conservation, they have been added to resins to decrease the weight of large filled regions. Examples are:
- K1 Scotchlite glass bubbles [3M]: made from soda-lime/ borosilicate glass;
- Zeeosphere: made from a white opaque ceramic.
