Eccostock®CPE Cross-Linked Polyethylene Rod and Sheet Stock CROSS-LINKED POLYETHYLENE STOCK Eccostock CPE is a cross-linked polyethylene rod and sheet stock. The material is thermosetting. It will not flow even when subjected to excessive and prolonged heat. 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. It can be used as a direct substitute for polytetrafluoroethylene with a consequent weight and cost savings. FEATURES AND BENEFITS
- Low dielectric loss
- Excellent machinability
- Good mechanical properties MARKETS
- Commercial Telecom
