3M™ Glass Bubbles K1, 210 LB

• Decreases density and increases buoyancy to help improve efficiency and may lower material costs
• Virtually insoluble in water or oil making them suitable for use in underwater applications
• Stable voids for low thermal conductivity and reduced dielectric constant
• Versatile use – adaptable to a variety of production processes
• Provides buoyancy in syntactic foam compositions
• Additive can easily be sanded in lightweight wall repair compounds

3M™ Glass Bubbles K1 are hollow glass microspheres that are ideal for a number of applications including – shallow (e.g. up to 2,000 feet of sea water) water flotation devices and lightweight wall repair compound. These low-cost, economical bubbles have a very low typical density (0.125 g/cc) and an isostatic crush strength of 250 psi.
