Tefzel ETFE 200
Tefzel ETFE 200 is a general-purpose fluoroplastic resin available in translucent, 2.5-mm (0.1-in.) pellets. Compared to other grades of Tefzel™ , its most unique features are an intermediate flow rate and a balance of properties that make it suitable for a variety of processes and demanding end uses.
Tefzel ETFE 200 is ideal for many end products, including electrical components, such as sleeving, coil forms, sockets, connectors, and switches; lab ware, such as tubing, valves, containers, and dishes; battery or instrument components that require chemical inertness; chemical service items, such as valve components, seal glands, pipe plugs, and corrugated tubing; and film.
Tefzel ETFE 200 can be processed by conventional, meltextrusion techniques and injection, compression, transfer, and blow molding processes. Compared to other grades of Tefzel, Tefzel ETFE 200 provides intermediate processing rates. Also, the melt viscosity of all grades of Tefzel is reduced with increasing shear rate; thus, permitting the use of pressure extrusions through narrow dies without requiring appreciable draw-down. Reciprocating screw injection molding machines are preferred. Corrosion-resistant metals should be used in contact with molten resin. Extruder barrels should be long, relative to diameter, to provide residence time for heating the resin to approximately 345 °C (650 °F).
Storage and Handling
The properties of Tefzel ETFE 200 resins are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and the formation of water condensation on the resin when it is removed from containers.
