Product Information
The K20 Glass Bubbles can be compounded in a variety of thermoset polymers to reduce the density of the composite. These composites can be incorporated into deep sea syntatctic foam for buoyancy modules to improve the uplift properties of a system at minimal foam volumes.
They offer good strength-to density ratio, making them suitable for a variety of applications: buoyancy, coatings, adhesives, sealants, and thermoset resins systems.
