nTefzel ™ ETFE HT-2202 is a special-purpose fluoroplastic resin available in 2.5-mm (0.1-in) pellets. Tefzel ™ ETFE HT-2202 is a modified ETFE resin designed to promote adhesion between polyamide resins and ETFE resins.Tefzel ™ ETFE HT-2202 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-2202 is an easy-to-process adhesive material. Tefzel ™ ETFE HT-2202 is inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. Recommended upper service is 150 °C (302 °F); useful properties are retained at cryogenic ranges. The level and stability of dielectric properties are excellent. Mechanical properties include outstanding high-impact strength, cut-through, and abrasion resistance.Typical End ProductsTefzel ™ ETFE HT-2202 is ideal for many end products, including electrical components, such as sleeving, coil forms, sockets, connectors, and switches; lab ware, multi-layer tubing, valves, containers, and fasteners; battery or instrument compo
