Fluoroplastic ETFE Resin

Get to know Everflon+™ ETFE C4003.

Everflon+™ ETFE C4003 resin combines the chemical and high-temperature resistance of Everflon™ ETFE with antistatic levels of electrical conductivity. Everflon+™ ETFE C4003 and the other Everflon™ ETFE 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 other fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.

Everflon+™ ETFE C4003 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 neat Everflon+™ ETFE C4003 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. The recommended upper service temperature is 175 °C; useful properties are retained at cryogenic ranges. Mechanical properties include outstanding impact strength, cut-through, and abrasion resistance.

The main advantage of Everflon+™ ETFE C4003 is that it has improved stress crack resistance and flexibility when compared to other static-dissipating Everflon+™ ETFE C4010 resins. To gain stress crack resistance.

Typical Applications

Everflon+™ ETFE C-4003 resin can be used to manufacture extruded tubing, pipe, and other profiles for hose; linings of components used in the chemical processing industries; industrial film; and injection- and blow-molded articles requiring superior electrical, chemical, and thermal properties and stress crack resistance.

Processing Guide

Everflon+™ ETFE C-4003 can be processed by conventional thermoplastic techniques, such as by melt-extrusion or injection, compression, transfer, and blow-molding processes.

Drying at 100–130 °C (212–266 °F) in a dehumidified oven for 4 hr is suggested to remove any absorbed moisture.

Reciprocating screw injection molding machines are preferred. Corrosion-re-sistant metals should be used in contact with molten resin from 300–345 °C (570–650 °F).

Precaution

Before using Everflon+™ ETFE C-4003 resin, refer to the Safety Data Sheet andthe latest edition of “The Guide to the Safe Handling of Fluoropolymer Resins”.

Open and use containers only in well-ventilated areas using local exhaust ventilation (LEV). Vapors and fumes liberated during hot processing of Everflon+™ ETFE C-4003 should be exhausted completely from the work area. Contamination of tobacco with these polymers must be avoided. Vapors and fumes liberated during hot processing that are not properly exhausted, or from smoking tobacco or cigarettes contaminated with Everflon+™ ETFE C-4003 , may cause flu-like symptoms, such as chills, fever, and sore throat. This may not occur until several hours after exposure and will typically pass within about 24 hours. Mixtures with some finely divided metals, such as magnesium or aluminum, can be flammable or explosive under some conditions.

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.
