We offer 3M Hollow Glass Microspheres for Thermal Insulation Applications. The high strength and low thermal conductivity (0.06 – 0.2 W•m-1•K-1 at 0°C)* of 3M™ Glass Bubbles make them ideal additives in pipeline and riser insulation. These inert particles are completely compatible with all other components of the insulating system, including polyurethane, polypropylene and epoxy. What''s more, these hollow glass microspheres are virtually insoluble in water…providing better utility in underwater applications.
Typical application area where Thermal Conductivity can be reduced: -
