Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours Company
Description
Tefzel ? ETFE 280 is a premium fluoroplastic resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel ? , its most unique features are relatively low flow rate, greatly enhanced flex life, and resistance to environmental stress.
Tefzel ? ETFE 280 and the other Tefzel ? fluoroplastics are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are high performance resins that can be processed at relatively high rates, compared with fluorocarbon resins. They aremechanically tough and offer an excellent balance of properties.
Tefzel ? ETFE 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 ? ETFE 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 flame rating is V-0 by the UL94 method. 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 ? 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.
