Fluoroplastic FEP Resin

FEP 4610/S

Get to Know FEP 4610

Everflon™ FEP 4610 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 Type I.

• non-aging characteristics,

• chemical inertness,

• exceptional dielectric properties,

• heat resistance,

• toughness and flexibility,

• low coefficient of friction,

• non-stick characteristics,

• negligible moisture absorption,

• low flammability,

• performance at temperature extremes,

• excellent weather resistance.

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.

Stress-crack resistance is an important element in establishing end-use performance. Extensive testing of wire and cable constructions is needed for definitive performance evaluation.

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.
