FEP 4610/S
Get to Know FEP 4610
Everflon™ FEP 4610 is a general-purpose grade and is used in many different applications. It can be melt-extruded, and is used for wire coating as primary insulation and, in certain cases, for cable jacketing. Cables insulated with Everflon™ FEP 4610 have met the requirements of Underwriters Laboratory UL910 Steiner Tunnel tests for installation in plenums without metal conduits.
Typical Applications
Typical Applications for Everflon™ FEP 46l0 is wire and cable insulation, small tubing, and injection molded parts.
Processing Guide
Everflon™ FEP fluoroplastic resin can be processed by conventional melt extrusion, and by injection, compression, and blow molding processes.
For smooth feeding to extrusion equipment, it is supplied in 3 mm (0.12 in) pellets.
The extruders and molding machines used for Everflon™ FEP should be constructed of high nickel alloy corrosion-resistant materials and be capable of operating at temperatures up to 400 °C (750 °F)
Precaution
Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to com-pletely 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 process-ing any fluoroplastics, read the Material Safety Data Sheet.
Handing & Package
Everflon™ FEP is packaged in 25-kg, single layer, plastic bags. For convenient shipment, orders of 1000-kg gallary are recommended.
The properties of Everflon™ FEP 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 contain-ers.
