ECCOSTOCK® HiK is a series of controlled dielectric constants materials ranging from 3 to 15. The power loss in a dielectric due to heating as a wave passes through it. It can be expressed as dielectric loss tangent or "loss factor". Low loss makes a good dielectric (ECCOSTOCK). High loss is an absorber (ECCOSORB), poor dielectric. Dielectric loss is low and the accuracy of the The ratio of the capacitance of a condenser filled with the material in question to that of the same condenser filled with vacuum. dielectric constant is less than 3%. The material does not support fungal growth per MIL-STD-810E, has low water absorption and low outgassing for space applications.
Intended for RF and microwave applications, ECCOSTOCK® HiK is primarily used for reducing the overall size of a waveguide by increasing the dielectric constant. It is also used in cavity tuning probes, patch antennas, and dielectric support pieces.
