FEP 4630HT

Get to know Everflon™ FEP 4630HT.

Everflonultra™ FEP 4630HT is a melt-processible fluoroplastic resin available in pellet form. It is a copolymer of tetrafluoroethylene, hexafluoropropylene and ppve,without additives, that meets the requirements of ASTM D 2116 Type II. With a relatively high melt flow rate and improved high frequency electrical properties,Everflonultra™ FEP 4630HT has been designed for high-speed extrusion of thin coatings on small-gauge wires.

Everflonultra™ FEP 4630HT has a higher melt flow rate than most other fluoroplastic resins. This permits higher extrusion speeds and easier processing, making Everflonultra™ FEP 4630HT a cost-effective alternative for producing thin-wall extrusions.
Everflonultra™ FEP 4630HT is designed and made to have improved dissipation factor at high frequencies, and to have significant plate-out resistance in melt extrusion.It is suitable as a solid insulator and as a foamed insulator when used with an appropriate nucleant in a nitrogen gas injection process.
Everflonultra™ FEP 4630HT is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of Everflonultra™ FEP 4630HT can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties. Everflonultra™ FEP 4630HT combines the processing ease
of conventional thermoplastics with many properties similar to those of PFA.
Properly processed products made from neat Everflonultra™ FEP 4630HT resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility,low coefficient of friction, nonstick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and excellent weather resistance.In a flame situation, products of Everflonultra™ FEP 4630HT resist ignition and do not promote flame spread. When ignited
by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke.

Typical Applications

Applications for Everflon™ FEP 4630HT include small diameter, thin wall wire and cable insulation; industrial film; and intricate or thin wall parts made by injection molding.

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

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 Cus-tomer Service Group. Also read the detailed information in the latest edition of the “Guide to the Safe Handling of Fluoropolymer Resins”.
