The precisely controlled particle size distribution and uniform spherical morphology of iM16K ensure excellent flow, reduced viscosity build-up and uniform dispersion in cementitious systems, polymers, composites, coatings, adhesives and sealants. Chemically inert and non-combustible, iM16K provides long-term stability and reliability in aggressive chemical, thermal and mechanical conditions.

The exceptionally high strength of iM16K glass bubbles allows them to withstand very high processing pressures encountered during polymer compounding, extrusion and molding, as well as extreme hydrostatic pressures experienced in deep-water and subsea environments. With an isostatic crush strength of approximately 16,000 psi, iM16K microspheres maintain structural integrity and density consistency under severe loads, offering an outstanding strength-to-density ratio.

In addition, 3M™ glass bubbles iM16K help to reduce overall weight, improve dimensional stability, reduce shrinkage and sink marks, and contribute to material and process cost savings through improved flow and optimized filler loading. They are ideal additive materials for high-performance applications across the automotive and heavy truck, aerospace, electrical, sports & leisure, electronics, appliances, and durable goods industries. iM16K glass bubbles are also highly valuable in construction products such as polymer/wood composites and siding, helping not only to reduce part weight, but also to improve dimensional stability and nail-ability, ensuring consistent installation and long-term service performance.
