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.
