    The thermal conductivity of 3M S32 glass bubbles is approximately 0.10 W·m-1·K-1 at 70°F (21°C). This low thermal conductivity contribution to syntactic foam pipe coatings makes S32 glass bubbles an ideal additive in insulation coatings for pipelines and production risers. The 2000 psi test strength of S32 glass bubbles means they can survive both the rigorous demands of processing and the enormous water pressure at depths up to about 3000 feet (900 meters) of seawater (using the industry accepted safety margin of 50%). Like all 3M glass bubbles, they are virtually insoluble in water or oil.
