Eccostock LoK

Light weight dielectric thermoset

Product Description

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.
