EFEP is a polymer unique to Daikin. It is a terpolymer of ethyelene, tetrafluoroethylene, and hexafluoropropylene. It was designed to have many of the mechanical properties of ETFE, but with a lower processing temperature, allowing it to be coextruded with conventional thermopostic polymers. EFEP is also designed to adhere to many conventional plastics such as polyamide, EVOH, and modified polyethylene without the use of adhesives or tie layers. It is used in monowall tubing, multilayer tubing, low permeation automotive fuel hose, catheters and blow molded bottles and containers. It can be extruded, injection molded and blow molded.
