美國杜邦ETFE  HT-2183 卡扣薄膜 閥門部件原材料 乙烯四氟乙烯共聚物

Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours Company

Tefzel ? ETFE HT-2183 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 a greatly enhanced flex life and resistance to environmental stress.

Tefzel ? HT-2183 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-2183 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 or thick sections for use at high temperatures.

Properly processed products made from neat Tefzel ? HT-2183 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. They are resistant to environmental stress cracking and have outstanding impact strength, cutthrough, 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-2183 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.
