  • Conductive Silver Metal Coated Hollow Glass Microspheres
  • M-40 - Silver-coated Hollow Glass Particles - Conductive Hollow Glass
  • M-60 - Silver-coated Hollow Glass Particles - Conductive Hollow Glass

Conductive hollow glass microspheres have low particle densities and so provide a significant weight reduction when used in place of conventional conductive fillers such as solid silver particles. A range of products offers particles with a variety of diameters, densities and crush strengths. HGMS-AG / HCMP-AG product lines were specifically designed for applications in biotechnology and as a tracer particle in Particle Image Velocimentry (PIV) which often require a true particle density higher than 1g/cm3 or just slightly lower at 0.9g/cm3.

HGMS-AG product line: >90% of particles are round and spherical

HCMP-AG product line: >80% of particles are round and spherical

Electromagnetic Shielding:

All of these products gave shielding of 45-55 dB at 3 GHz when incorporated at 40% by volume into an acrylic resin film of 50-100 μm thickness.

M-18 conductive spheres gave shielding of 45dB at only 20% loading.
