Get to Know FEP 4603X

Everflonultra™ FEP 4603X is a melt-processible copolymer of TFE,HFP and PPVE, without additives,that meets the requirements of ASTM D 2116 Type IV.

It offers the excellent combination of properties characteristic of Everflon™ 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, and excellent weather resistance.

Everflonultra™ FEP 4603X 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 crackresistance, it can be processed at faster rates and higher extrusion line speeds than many FEP grades with comparable stress crack resistance performance.

Typical Applications

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.

Processing Guide

Everflonultra™ FEP fluoroplastic resin can be processed by conventional melt extrusion, and by injection, com-pression, 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 corro-sion-resistant materials and be capable of operating at temperatures up to 400 °C (750 °F).

Precaution

Industrial experience has proven that adequate ventilation, in properly maintained processing and handling areas, will eliminate known hazards to personnel. Resin containers should be opened and used in well-ventilated areas.

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 processing any fluoroplastics, read the Material Safety Data Sheet, available upon request from our Customer Service Group. Also read the detailed information in the latest edition of the “Guide to the Safe Handling of Fluoropolymer Resins”.

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 containers.
