Get to Know FEP 4603

Everflon™ FEP 4603 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 Type IV. It offers the excellent combi-nation of properties characteristic of Ever-flon™ fluoroplastic resins:

non-aging characteristics,
chemical inertness,
exceptional dielectric properties,
low flammability, heat resistance,
toughness and flexibility,
low coefficient of friction,
non-stick characteristics,
negligible moisture absorption,
excellent weather resistance.

Everflon™ FEP 4603 is used in the chemical industry for applications, such as chemical linings, bellows, valve components, pipes, and tubing. In demanding wire and cable applications, requiring a very high degree of stress crack resistance, it can be used as a material for jacketing.

Thanks to its combination of viscosity and stress crack resistance, it can be processed at faster rates and higher extrusion line speeds than many Everflon™ FEP grades with comparable stress crack resistance performance.

Typical Applications

Typical Applications for Everflon™ FEP 4603 is tubes, piping, linings, bellows, valves, and other components for the chemical industry. Jackets for wire and cable applications demanding a high degree of stress crack resistance. More information could visit www.everflon.com or Everflon™ FEP Grade of selector of wire and cable.

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.
