ECCOSTOCK® CPE is a cross-linked polyethylene that is available in rod or sheet stock. The material is thermosetting with excellent dimensional stability; it will not flow even when subjected to excessive and prolonged heat. However, the surface may darken with no effect on the bulk properties of the material. Physical properties of ECCOSTOCK® CPE are similar to those of polyethylene at room temperature and can be used as a direct substitute for polytetrafluoroethylene with a consequent weight and cost savings.
ECCOSTOCK® CPE has excellent electrical properties and can be used for insulators, cavity tuning probes, patch antennas and dielectric support pieces of all kinds.
