CONDUCTOSPHERES™ are a range of lightweight conductive fillers consisting of hollow glass microspheres coated with a thin layer of metal.
They can be incorporated into coatings, composites and adhesives to provide these materials with electrical conductivity and shield against electromagnetic interference (EMI).
Due to their hollow core, CONDUCTOSPHERES have very low particle densities and so provide significant weight reductions over conventional metal fillers.
The CONDUCTOSPHERES range (more info) includes silver and nickel products with a variety of particle sizes, densities and crush strengths.
