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™  ETFE HT-2183 and the other Tefzel™  fluoroplastics  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. Table 1 shows  typical property data for Tefzel™  ETFE HT-2183. 

Tefzel™  ETFE 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™ ETFE 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, 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.
