Chemours Tefzel™ ETFE HT-2188 Special purpose fluoroplastic resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; ETFE/ECTFE; Fluorocarbon ETFE/ECTFE, Molded/Extruded
Material Notes:	Tefzel™ ETFE HT-2188 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, low melting point, and high flexural endurance. Tefzel™ ETFE HT-2188 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. Tefzel™ ETFE HT-2188 is ideal for many end products, including electrical components, such as sleeving, coil forms, sockets, connectors, and switches; lab ware, such as tubing, valves, containers, and fasteners; battery or instrument components that require chemical inertness; and mechanical parts.
