Tefzel ™ ETFE HT-2183 is a premium fluoroplastic resin availablein translucent, 2.5-mm (0.1-in) pellets. Compared with other gradesof Tefzel ™ , its most unique features are a greatly enhanced flexlife and resistance to environmental stress.
Tefzel ® HT-2183 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 other fluorocarbonresins. They are mechanically tough and offer an excellent balanceof properties.
Tefzel ® HT-2183 is preferred for applications where otherthermoplastics are lacking in mechanical toughness; broad thermalcapability; ability to meet unusual thermal, mechanical, andchemical environmental extremes; or limited by fabricatingproblems. Examples are components and linings for the chemicalindustry and molded parts with metal inserts or thick sections foruse at high temperatures.
Properly processed products made from neat Tefzel ® HT-2183 areinert to most solvents and chemicals, hydrolytically stable, andweather-resistant. The recommended upper service temperature is155°C (311°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. They are resistant toenvironmental stress cracking and have outstanding impact strength,cutthrough, and abrasion resistance. Statements, or data, regardingbehavior in a flame situation are not intended to reflect hazardspresented by this or any other material when under actual fireconditions.
Typical End Products
Tefzel ® HT-2183 is ideal for many end products, including chemicalservice items, such as lined valves and fittings, pump housings andimpellers, column packings, and other abrasion-resistant linings;high-temperature electrical components and insulation; fasteners,corrugated tubing, and duct work; and film.
