    Product Details

    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.

    K1 is the Glass Bubbles grade with the lowest density and designed for a variety of applications where very low density and low thermal conductivity is needed. Typical applications are lighweitght buoyancy modules, wall repair compounds, thermal insulating paints, construction materials, and emusion explosives.
