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™ ETFE HT-2185 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  fluorocarbon resins. They are mechanically tough and offer  an excellent balance of properties. Table 1 shows typical  property data for Tefzel™ ETFE HT-2185. 

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

Properly processed products made from neat Tefzel™  ETFE 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.
