Solutions: Low Loss Dielectrics


Eccostock PP


Home - Products - Absorbers - Low Loss Dielectrics

Flexible closed cell dielectric foam

Due to the low dielectric constant, the materials are essentially transparent to electromagnetic energy. It offers excellent thermal insulation. Eccostock PP is lightweight and will return to its normal thickness after being compressed. It can be heat sealed to form blocks of material or to make contoured pieces that can be draped over complex objects. Eccostock PP can be used as radomes, blankets, and coverings where radar transparency is desired as well as spacer in electronic.

Eccostock HIK 500


Home - Products - Absorbers - Low Loss Dielectrics

High temperature tuned low loss dielectric stock

When subjected to high temperatures, the surface will darken. This however has no adverse effect. Eccostock HiK500F offers low moisture absorption and low outgassing properties for space applications. It is used in cavity tuning probes, patch antennas, and dielectric support pieces as well as waveguide

Eccostock LoK


Home - Products - Absorbers - Low Loss Dielectrics

Light weight dielectric thermoset

Eccostock LOK weighs only about half that of polystyrene and one quarter that of polytetrafluorethylene, making it first choice for weight sensitive application. It has better dimensional stability than other low loss plastics and exhibit very good moisture resistance It will not cold flow, nor will flow when heat is applied. Eccostock Lok is of benefit in application like coaxial, waveguide and antenna support to minimize reflections in transmission line thanks to its low dielectric constant.
