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 the first choice for weight sensitive applications. It has better dimensional stability than other low loss plastics and exhibits very good moisture resistance. It will not cold flow, nor will it flow when heat is applied. Eccostock LoK benefits applications such as coaxial, waveguide, and antenna support. It minimizes reflections in transmission lines thanks to its low dielectric constant.
