3M™ Glass Bubbles K15, 110 kg (242.5 lb), Box

3M™ Glass Bubbles K15 are hollow glass spheres with a typical density of 0.15 g/cc and isostatic crush strength of 300 psi. These spheres are designed for use in a variety of oil and gas applications including drill riser buoyancy modules, buoys and moorings. Our K15 bubbles produce strong, stable voids with low thermal conductivity, helping coatings achieve the necessary compressive strength.

With low density (0.15 g/cc) and isostatic strength good to 300 psi, 3M glass bubbles K15 are ideal for use in a variety of water buoyancy applications, including additives in buoys and moorings. Like all 3M glass bubbles, K15 bubbles are compatible thermoset resins like polyurethane and epoxy, and are virtually insoluble in water.

• Lower viscosity, improved flow
• Increased filler loading, reduced cost
• VOC reduction
• Chemical stability and inertness
