Product Details

3M™ Glass Bubbles S38XHS have a density of 0.38 g/cm3 and an isostatic crush strength of 5500 psi / 379 bar with a minimum survival of 90%. The S Series glass bubbles have smaller particle sizes than the K Series.

3M™ Glass Bubbles S38XHS (rated to 5500 psi / 379 bar) have a minimal fractional survival rate of 90% for consistent performance and good survivability, they can survive both the rigorous demands of processing and the enormous water pressure at depth. In turn, their low thermal conductivity makes them ideal additives in insulation for pipelines and production risers helping to ensure that hot oil continues to flow to the surface, rather than cooling and slowing. Like all 3M glass bubbles, S38XHS are virtually insoluble in water or oil.
