Chemours Tefzel™ ETFE HT-2202HS Special purpose fluoroplastic resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; ETFE/ECTFE; Fluorocarbon ETFE/ECTFE, Molded/Extruded
Material Notes:	Tefzel™ ETFE HT-2202HS is a special-purpose fluoroplastic resin available in 2.5-mm (0.1-in) pellets. Tefzel™ ETFE HT-2202HS is a high flow modified ETFE resin designed to promote adhesion between polyamide resins and ETFE resins. Tefzel™ ETFE HT-2202HS 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. Tefzel™ ETFE HT-2202HS is an easy-to-process adhesive material. Tefzel™ ETFE HT-2202HS is inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. Applications: electrical components, such as sleeving, coil forms, sockets, connectors, and switches; lab ware, multilayer tubing, valves, containers, and fasteners; battery or instrument components that require chemical inertness; and mechanical parts.
