3M™ Glass Bubbles S42XHS is high-strength additives for polymers made from a water-resistant and chemically stable soda- lime-borosilicate glass. 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. The S42XHS glass bubbles have isostatic crush strengths of 8000 psi with a minimum of 90% survival.
