3M XLD3000 Glass Bubbles

3M™ Glass Bubbles XLD3000 are high-strength additives for polymers made from a water-resistant and chemically stable soda-lime-borosilicate glass. These hollow glass bubbles 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 XLD3000 glass bubbles can withstand both the high processing pressure of polymer extrusion and the pressure of seawater in many applications. The XLD3000 glass bubbles have isostatic crush strengths of 3,000 psi with a minimum of 90% survival.Information provided by 3M
