ECCOSTOCK® HT0003 is a low dielectric loss, high temperature, rigid stock for a variety of electrical insulating applications. This material system is a thermosetting hydrocarbon resin that is filled with polytetrafluoroethylene giving it many of the desirable features of Teflon®. Properties include low loss, low friction surface, chemical resistance, etc. It will not flow at high temperatures but the surface may darken with no effect on the bulk properties of the material. It can be bonded without etching. As the name suggests the dissipation factor for this material is .0003.
ECCOSTOCK® HT0003 is used for a variety of electrical insulating applications, stand-offs, dielectric windows, cavity tuning probes, patch antennas and support pieces. ECCOSTOCK® HT0003 is easy to machine with standard cutting and grinding tools.
