Description
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. Table 1 shows typical property data for Tefzel ™ ETFE HT-2188.

The relatively high flow rate and low melt point of Tefzel ™ ETFE HT-2188 makes it uniquely suitable for high-speed processing, especially for extruded coatings or films, and injection molding of slender, thin-walled, or intricate shapes. It has a relatively low flexural modulus and high flexural endurance that makes it suitable for a variety of demanding applications.

Properly processed products made from neat Tefzel ™ ETFE HT-2188 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.

Typical End Products
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.
