3M™ Glass Bubbles K20 are engineered hollow glass microspheres made from soda-lime borosilicate glass. Supplied as a lightweight white powder, they are intended for incorporation into compatible resin and polymer systems where reduced composite density is required.
The K20 grade combines low density with water and oil resistance. Its hollow spherical form can support higher filler loading, improved flow characteristics and reduced shrinkage in suitable formulations.
- 3M™ Glass Bubbles K20 grade
- Hollow soda-lime borosilicate glass microspheres
- Typical true density: 0.20 g/cm³
- Typical median particle diameter: 60 µm
- Typical isostatic crush strength: 3.45 MPa, with 80% minimum fractional survival
- Nominal pack weight: 0.45 kg (1 lb)
Suitable for maintenance, repair and composite workshop applications where a low-density filler is specified by the applicable material process or engineering data. Review the relevant 3M technical and safety documentation before handling and use.
