High quality glass microspheres for research and development are always in high demand.? In an effort to better serve scientists Cospheric recently added a complete line of high quality borosilicate microspheres, and microbeads.
Borosilicate glass offers? advantages over standard soda lime glass microbeads.
- Roundness is >90%?? (Soda lime >85%)
- Density is the lowest of most glasses at 2.2g/cc? (Soda Lime 2.5g/cc)
- Very low thermal expansion coefficient? 32×10-7/?C?? (for 30-300?C)?? (Soda Lime:? 90×10-7/?C)
The high roundness, and low thermal expansion make borosilicate spheres an excellent candidate for use as spacers in epoxy bond lines, or other applications which require stability over a wide temperature range.
Borosilicate glass spheres are now offered in narrow size ranges from 0.03mm to 0.2mm with greater than 90% of the particles in range.
- 27-32 micron? (0.3mm)
- 32-38 micron (0.035mm)
- 38-45 micron (0.04mm)
- 45-53 micron (0.05mm)
- 53-63 micron (0.06mm)
- 63-75 micron (0.07mm)
- 75-90 micron (0.08mm)
- 90-106 micron (0.1mm)
- 106-125 micron (0.12mm)
- 125-150 micron (0.15mm)
- 150-180 micron (0.18mm)
- 180-212 micron (0.2mm)
