Get to Know Everflon™ FEP 4610.

Everflon™ FEP 4610 is a general-purpose grade and is used in a wide range of applications. It can be processed by melt extrusion and is applied in cable coating as primary insulation and, in certain cases, for cable outer jackets. Cables insulated with Everflon™ FEP 4610 meet the requirements of Underwriters Laboratory’s Steiner Tunnel UL910 test for installation in plenum spaces without metal conduits.

Typical Applications.

Typical Applications for Everflon™ FEP 4610 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.

Handling & Packing.

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.
