Dupont Tefzel HT-2202 Fluoropolymer Plastic ETFE Virgin Resin Pellet Powder

Tefzel™ ETFE (ethylene-tetrafluoroethylene) resins are melt-processable copolymers with a reputation for excellent physical toughness and resistance to radiation, chemicals, UV, and extreme temperatures. They can be customized for desired color, reinforcement, and conductivity levels, allowing them to be used in a variety of high-performance products and components.

Available as pellets or powder, Tefzel™ ETFE resins have multiple applications, which include:

• Electrical insulation and heat-shrinkable tubing
• Wire and cable, including wrapped computer terminations, heavy power circuits, steel mill cables, airframe wire, downhole well logging cable, and rapid transit car and locomotive control wire
• Load-bearing applications in abusive environments
• Cable and hydraulic line clamps, cable straps, and other fasteners
• Valve linings
• Pressure-sensitive tapes, flexible printed circuits, liquid pouches, and other constructions needing a film form
• Biomedical and labware equipment, including oxygen respirator components, blood analyzer valves, evaporating dishes, and centrifuge tubes

Whether powder or pellet, Tefzel™ ETFE resins offer relatively low melting points and high-melt flow rates (MFRs), making them easy to process by conventional melt-extrusion techniques and injection-, compression-, transfer-, rotational-, and blow-molding processes.

Other characteristics of Tefzel™ ETFE resins include:

• Low wear factor (1/10 of reinforced nylon)
• High-impact strength and dimensional stability
• Heat resistance with a rating for temperatures up to 150 °C (302 °F) based on the 20,000-hour criterion and good creep resistance
• Low flammability
• Specific gravity of 1.7
• Strong weathering capabilities (up to at least 20 years)
• Low-moisture absorption
• UV resistance
• Resistance to solvents, acids, and bases

DuPont™ Tefzel® fluoropolymer resins offer mechanical strength and toughness along with resistance to heat and chemicals. In addition, they provide easy processing, high specific dielectric strength, and a low coefficient of friction. For these reasons, Tefzel® resins are widely used to make compact wire and cable constructions that provide long, reliable service in demanding environments.

Tefzel® 750 retains the traditional characteristics of Tefzel® resins while providing some new property advantages, including increased flexibility and improved retention of properties after aging at elevated temperatures, higher limiting oxygen index, and long-term service life at higher temperatures than other Tefzel® resins.

Underwriters Laboratories, Inc. (UL) has rated wire insulated with Tefzel® 750 (10 mil for 600V, 6 mil for 300V) for service in appliances at a maximum continuous operating temperature of 200°C (392°F). This rating was determined under the guidelines of UL Subject 758 for appliance wiring material. Upper service temperatures for other applications should be determined under the guidelines for those applications. Temperature ratings may not be the same as the rating for appliance wire because the test procedures are different.
