Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours Company
Tefzel ? ETFE HT-2181 is a general-purpose fluoroplastic resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with 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. Table 1 shows typical property data for Tefzel ? ETFE HT-2181.
Tefzel? HT-2181 and the other Tefzel? fluoropolymers are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are high-performance resins that can be processed at relatively high rates compared with other fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.
Tefzel? HT-2181 can perform successfully in applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet difficult environmental conditions, or limited by fabricating problems.
Properly processed products made from neat Tefzel? HT-2181 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. The recommended upper service temperature is 155°C (311°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. Mechanical properties include outstanding impact strength, cut-through, and abrasion resistance.
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 ? HT-2181 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.
