Hollow Glass Microspheres 3M Sctochlite K-15


Hollow Glass Microspheres made of sodalime borosilicate practically insoluble in water and white powdery material that floats on water.



  • Product Type : 3M Sctochlite K-15

  • True Density : 0,15 g/cc
  • Crush Strength : 300 Psi


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.
