ETFE美国杜邦HT-2185乙烯-四氟乙烯共聚物机械韧性好GenericName: 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 resinavailable in translucent, 2.5-mm (0.1-in) pellets. Compared withother grades of Tefzel™, it has a higher flow rate.

Tefzel® HT-2185 and the other Tefzel® fluoropolymers are meltprocessible, modified copolymers of ethylene andtetrafluoroethylene. They are high-performance resins that can beprocessed at relatively high rates compared with fluorocarbonresins. They are mechanically tough and offer an excellent balanceof properties.

The relatively high flow rate of Tefzel® HT-2185 makes it uniquelysuitable for high-speed processing, especially for extrudedcoatings and injection molding of slender, thin-walled, orintricate shapes. Molded or extruded products made from Tefzel®HT-2185 are preferred for uses that do not involve significantflexural or tensile stress at elevated temperatures. Higherviscosity products such as Tefzel® HT-2181 and Tefzel® HT-2183 arepreferred for these applications.

Properly processed products made from neat Tefzel® HT-2185 areinert to most solvents and chemicals, hydrolytically stable, andweather-resistant. The recommended upper service temperature is150°C (302°F); useful properties are retained at cryogenic ranges.The level and stability of dielectric properties are excellent, andthe flame rating is V-0 by the UL94 method. Mechanical propertiesinclude outstanding impact strength, cut-through, and abrasionresistance.

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 ® HT-2185 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 fasteners; battery or instrument components thatrequire chemical inertness; and mechanical parts.
