ETFE美國杜邦HT-2185乙烯-四氟乙烯共聚物機械韌性好Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours Company

Tefzel? ETFE HT-2185 is a special purpose fluoroplastic resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel?, it has a higher flow rate.

Tefzel? HT-2185 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 fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.

The relatively high flow rate of Tefzel? HT-2185 makes it uniquely suitable for high-speed processing, especially for extruded coatings and injection molding of slender, thin-walled, or intricate shapes. Molded or extruded products made from Tefzel? HT-2185 are preferred for uses that do not involve significant flexural or tensile stress at elevated temperatures. Higher viscosity products such as Tefzel? HT-2181 and Tefzel? HT-2183 are preferred for these applications.

Properly processed products made from neat Tefzel? HT-2185 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. The 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. 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-2185 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 fasteners; battery or instrument components that require chemical inertness; and mechanical parts.
