Conductive Microspheres
Half-Coated Spheres
ConductospheresConductive Microspheres (Silver Coated)  "Conductospheres"

Coating: Highly Conductive Silver Coating
Core:
Hollow glass microspheres
Standard Particle Sizes:  5-30um to 25-120um (Custom Ranges Also Available)
Densities:   0.16, 0.32, 0.49, 0.62, & 0.72g/cc
Crush Strengths:  300psi to 28,000 psi

These highly electrically conductive microspheres can be used as a filler that is lighter than solid silver in paints, adhesives and composities to provide electrical conductivity.  Loadings as low as 20% by weight can achieve sufficient shielding against electromagnetic interference (EMI).
