Everflon™ FEP 4630 is a melt-processible fluoroplastic resin available in pellet form. It is a copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116 Type II. With a relatively high melt flow rate and excellent electrical properties, Everflon ™ FEP E4630 has been specifically designed for high-speed extrusion of thin coatings on small-gauge wires for twisted-pair constructions. This resin provides the electrical and mechanical properties needed for low voltage applications.

In addition, Everflon™ FEP 4630 has a higher melt flow rate than most other fluoroplastic resins. This permits higher extrusion speeds and easier processing, making Everflon™ FEP 4630 a cost-effective alternative for producing thin-wall extrusions.

Everflon™ FEP 4630 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.

Everflon™ FEP 4630 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 Everflon™ FEP 4630 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. Everflon™ FEP E4630 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

Properly processed products made from neat Everflon™ FEP 4630 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 resistancen a flame situation, products of Everflon™ FEP 4630 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.
