Overview

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.
