Eccostock®HT0003

High Temperature, Low Loss Rod and Sheet

HIGH TEMPERATURE LOW LOSS MATERIAL

Eccostock HT0003 is a rigid, low loss, high temperature, inert material. It is based on a

thermosetting hydrocarbon resin and is filled with polytetrafluoroethylene giving it many of

the desirable features of Teflon®. These include low loss, low friction surface, chemical

resistance, etc. Eccostock HT0003 will not flow at high temperatures, but the surface may

darken with no effect on the bulk properties of the material.
