ECCOSTOCK^® HiK Powder is a series of granular, free flowing powders of adjusted dielectric properties. These products are typically used for R&D simulation work. These powders are distinguished by having an extremely stable bulk density. These powders are also relatively unaffected by changes in temperature and humidity and are reusable.

ECCOSTOCK^® HiK Powders are used to fill complex shapes for microwave experiments.  Devices can be immersed in the dielectric powders to test the effect of special dielectric mediums.  For example, an antenna can be immersed in ECCOSTOCK^® HiK Powder (K=10) and operated to simulate a re-entry plasma.  Waveguides and cavities can also be filled to test the effect of dielectric loading.
