Description
Tefzel ™ ETFE 200 is a general-purpose fluoroplastic resinavailable in translucent, 2.5-mm (0.1-in.) pellets. Compared toother grades of Tefzel ™ , its most unique features are anintermediate flow rate and a balance of properties that make itsuitable for a variety of processes and demanding end uses.

Tefzel ™ ETFE 200 and the other Tefzel ™ fluoroplastics are meltprocessible, modified copolymers of ethylene andtetrafluoroethylene. They are high-performance resins that can beprocessed at relatively high rates, compared to fluorocarbonresins. They are mechanically tough and offer an excellent balanceof properties. Tefzel ™ ETFE 200 can perform successfully inapplications where other thermoplastics are lacking in mechanicaltoughness, broad thermal capability, ability to meet difficultenvironmental conditions, or limited by fabricating problems.

Properly processed products made from virgin Tefzel ™ ETFE 200 areinert to most solvents and chemicals, hydrolytically stable, andweather-resistant. Recommended upper service temperature is 150 °C(302 °F); useful properties are retained at cryogenic ranges. Thelevel and stability of dielectric properties are excellent, and theflame rating is V-0 by the UL94 method. Mechanical propertiesinclude outstanding impact strength, cut-through, and abrasionresistance. High energy radiation resistance meets IEEE 383, andthe resin is approved for nuclear power plant use.

Statements, or data, regarding behavior in a flame situation arenot intended to reflect hazards presented by this or any othermaterial when under actual fire conditions.

Typical End Products
Tefzel ™ ETFE 200 is ideal for many end products, includingelectrical components, such as sleeving, coil forms, sockets,connectors, and switches; lab ware, such as tubing, valves,containers, and dishes; battery or instrument components thatrequire chemical inertness; chemical service items, such as valvecomponents, seal glands, pipe plugs, and corrugated tubing; andfilm.
