ETFE XL4010

Get to know Everflon^ultra™ ETFE XL4010.

Everflon^ultra™ ETFE XL4010 or Irradiation Cross-Linked Ethylene Tetrafluoroethylene, is a natural off-white high-performance fluoropolymer resin used for wire and cable insulation.

Everflon^ultra™ ETFE XL4010 products are compounded with a cross-linking agent in a middle melt Everflon^ultra™ ETFE 4010 polymer base It is produced by adding radiation crosslinking sensitizers, antioxidants, stabilizers, and other additives to ethylene-tetra fluoroethylene copolymer, followed by a radiation cross-linking process. This process gives XL-ETFE exceptional flame retardancy, high & low temperature resistance, chemical resistance, mechanical strength, aging resistance, radiation resistance, etc.

Everflon^ultra™ ETFE XL4010 complies with MIL-W-22759 (now SAE AS22759) and GJB-773 standards. It is lightweight and has excellent high and low temperature resistance, good mechanical and electrical properties, and chemical resistance. Moreover, it is easy to process and has a wide irradiation window.

Everflon^ultra™ ETFE XL4010 can withstand temperatures from -50°C up to 230°C. Its good processing adaptability makes it suitable for extrusion, injection molding, powder coating, filming, heat-sealing, composition with rubber, and other secondary processes. Moreover, XL-ETFE wires have high radiation resistance due to the irradiation cross-linking process.

Typical Applications

After extrusion, Everflon^ultra™ ETFE XL4010 needs to be cross-linked by electron beam irradiation. Once cross-linked the compound’s mechanical properties, such as scrape abrasion, cut-through resistance, and tensile strength are increased. Thermal properties, such as temperature rating and flammability, of the cross-linked compound are also improved. This makes Everflon^ultra™ XL-ETFE suitable for aerospace and aviation applications.

Processing Guide

Everflon^ultra™ ready-to-use XL-ETFE can be processed using conventional fluoropolymer extrusion techniques under standard Everflon™ETFE operating parameters. Be aware that the cross-link agent is volatile and will degrade if processing temperatures are too high or residence time is too long. Care should be taken to provide adequate ventilation.

Contact Everflon^ultra™ technical service if you have any questions regarding processing.

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.

Package

The properties of Everflon™ ETFE resin are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and water condensation on the resin when it is removed from containers.
Everflon™ ETFE is supplied as pellets and is available in 20-kg multilayer bags with an integral polyethylene liner.
