DuPont™ Tefzel® 280 fluoropolymer is a premium resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel®, its most unique features are a relatively low flow rate, a greatly enhanced flex life, and resistance to environmental stress. Tefzel® 280 and the other Tefzel® fluoropolymers are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are highperformance resins that can be processed at relatively high rates compared with fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties. Tefzel® 280 is preferred for applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet unusual thermal, mechanical, and chemical environmental extremes, or limited by fabricating problems. Examples are components and linings for the chemical industry and molded parts with metal inserts of thick sections for use at high temperatures. Properly processed products made from neat Tefzel® 280 are inert to most solvents and chemicals, hydrolytically stable, and weather resistant. Recommended upper service temperature is 150°C (302°F); useful properties are retained at cryogenic ranges. The level and stability of dielectric properties are excellent and the UL94 method flame rating is V-0. They are resistant to environmental stress cracking and have outstanding impact strength, cut-through and abrasion resistance. High-energy radiation resistance meets IEEE 383 and the resin is approved for nuclear power plant use. Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions. Typical End Products Tefzel ® 280 is ideal for many end products, including chemical service items, such as lined valves and fittings, pump housings and impellers, column packings and other abrasion resistant linings; high temperature electrical components and insulation; fasteners, corrugated tubing and duct work; and film. Tefzel® 280 is ASTM D3159 Type I, Grade 1.
