3M™ Glass Bubbles S42XHS

3M™ Glass Bubbles S42XHS have a density of 0.42 g/cm3 and an isostatic crush strength of 8000 psi / 551 bar. The S Series glass bubbles have smaller particle sizes than the K Series.

These hollow glass microspheres can be compounded with a variety of polymers to reduce the overall thermal conductivity of the composite. These composites can be coated or incorporated into deep sea oil pipelines to improve the flow assurance properties of the system. The high strength of S42XHS glass bubbles can withstand both the high processing pressure of polymer extrusion and the pressure of seawater in many applications. Like all 3M glass bubbles, S42XHS glass bubbles are virtually insoluble in water or oil.
