Fluoroplastic ETFE Resin

Get to know Everflon™ ETFE 4010.

Everflon™ ETFE 4010 is a general-purpose fluoroplastic resin available in translucent, 2.5-mm (0.1-in.) pellets. Compared to other grades of Everflon™ ETFE , its most unique features are an intermediate flow rate and a balance of properties that make it suitable for a variety of processes and demanding end uses.

Everflon™ ETFE 4010 and the other Everflon™ fluoroplastics are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are high-performance resins that can be processed at relatively high rates, compared to fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties. Everflon™ ETFE 4010 can perform successfully in applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet difficult environmental conditions, or limited by fabricating problems

Properly processed products made from virgin Everflon™ ETFE 4010 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. 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. High energy radiation resistance meets IEEE 383, and the resin is approved for nuclear power plant use. 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. and the flame rating is V-0 by the UL94 method. Mechanical properties include outstanding impact strength, cut-through, and abrasion resistance.

Typical Applications

Everflon™ ETFE 4010 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 dishes; battery or instrument components that require chemical inertness; chemical service items, such as valve components, seal glands, pipe plugs, and corrugated tubing and film.

Processing Guide

Everflon™ ETFE 4010 can be processed by conventional, melt-extrusion techniques and injection, compression, transfer, and blow molding processes. Compared with other grades of Everflon™ ETFE, Everflon™ ETFE 4010 provides intermediate processing rates. . Also, the melt viscosity of Everflon™ ETFE is reduced with increasing shear rate; thus, permitting the use of pressure extrusions through narrow dies without requiring appreciable drawdown. Reciprocating screw injection molding machines are preferred. Corrosion-resistant metals are recommended for contact with molten resin. Extruder barrels should be long, relative to diameter, to provide residence time for heating the resin to approximately 340 °C (640 °F).

Precaution

Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to completely remove all fumes and vapors from the processing area. In addition, care should be exercised to avoid the contamination of cigarettes and other forms of smoking tobacco when using fluoroplastic resins. Before processing any fluoroplastics, read the Material Safety Data Sheet.

Handing & Package

The properties of Everflon™ ETFE esins are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and the formation of water condensation on the resin when it is removed from containers. Everflon™ ETFE fluoroplastic resins are packaged in 20-kg (44-lb) plastic bags.
