Coating: Highly Conductive Silver Coating Core:Hollow glass microspheres Standard Particle Sizes:5-30um, to 10-95um, to 25-120um (Custom Ranges Also Available) Densities:0.16g/cc, 0.32g/cc, 0.49g/cc, 0.62g/cc, & 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).
