ECCOSTOCK LoK

Description Frequency Range Key Features Thickness Service Temp Indoor/Outdoor
Low loss, low dielectric, low density thermoset plastic 60 Hz to 10 GHz dk: 1.7, loss:.004, low CTE, will not flow, low water absorption 0.3 cm to 7.6 cm -70°C to 150°C In

ECCOSTOCK® LoK is a low The power loss in a dielectric due to heating as a wave passes through it. It can be expressed as "dielectric loss tangent" (power factor) or "loss factor". Low loss makes a good dielectric (ECCOSTOCK dielectric materials). High loss is an absorber (ECCOSORB), poor dielectric.dielectric loss, low The ratio of the capacitance (ability to store electrical energy) of a condenser filled with the material in question to that of the same condenser filled with vacuum.dielectric constant material made of lightweight thermosetting plastic for RF and microwave applications.  It weighs only about half that of polystyrene and one quarter that of polytetrafluoroethylene.  Its dimensional stability is better than that of other low loss plastics, it has a very low thermal expansion coefficient and will not flow under cold or hot temperatures.  It is also completely unicellular and not affected by moisture.

ECCOSTOCK
® LoK is specifically designed for use in coaxial, waveguide and antenna support applications.  Due to the low dielectric constant, reflections in transmission lines are minimized.  RF coils wound on ECCOSTOCK® LoK exhibit a higher The ratio of the stored versus transmitted energy. For a capacitor "Q" defines performance. For an enclosure where microwave circuits are operating, Q impedes the performance of a device.Q than when wound on polystyrene or other plastic stock.  Soldering iron temperatures will not soften ECCOSTOCK® LoK and will only slightly degrade in the immediate area of contact.
