DESCRIPTION

High-Performance, Mechanically Durable Resins
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 also 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

Features and Benefits

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 FEPD 121 is an off-white aqueous fluorinated ethylene propylene (FEP) dispersion stabilized with a non-ionic surfactant. It is a general-purpose dispersion that can be used to impart some the unique properties of FEP to end products that would be difficult to make using traditional melt extrusion processes. It can be used to coat or impregnate porous structures or to make thin films. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive.

The FEP resin in FEPD 121 is a melt flowable thermoplastic, providing superior properties typical of fluoropolymer resins: retention of properties after service at 204 °C (400 °F) and useful properties at -240 °C (-400 °F).

FEPD 121 aqueous dispersion provides:
* inertness to nearly all industrial chemicals and solvents
* stability at high temperatures
* excellent dielectric properties
* excellent weatherability
