Glass Bubbles
Glass Bubbles

3M™ Glass Bubbles are inert particles that offer high strength and low thermal conductivity, and are compatible with all other components of pipeline and riser insulating systems, including polyurethane, polypropylene and epoxy.

3M™ Glass Bubbles are hollow glass micro spheres with a high strength to density ratio. Lightweight but endowed with sufficient strength for processing survival, 3M™ Glass Bubbles facilitate potential enhancements like high filler loading, reduced warping / shrinkage, sandability and more.
