Typical Applications
Applications for Teflon ™ FEP 9898 include small diameter, thin wall wire and cable insulation; industrial film; and intricate or thin wall parts made by injection molding.
Description
Teflon ™ FEP 9898 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 improved high frequency electrical properties, Teflon ™ FEP 9898 has been designed for high-speed extrusion of thin coatings on small-gauge wires. Table 1 shows the typical property data for Teflon ™ FEP 9898.
As shown in Table 1, this resin provides the electrical and mechanical properties needed for low voltage applications. In addition, Teflon ™ FEP 9898 has a higher melt flow rate than most other fluoroplastic resins. This permits higher extrusion speeds and easier processing, making Teflon ™ FEP 9898 a cost-effective alternative for producing thin-wall extrusions.
Teflon ™ FEP 9898 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.
Teflon ™ FEP 9898 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 Teflon ™ FEP 9898 can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperaturesprovides a superior balance and level of end-use properties. Teflon ™ FEP 9898 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.
Properly processed products made from neat Teflon ™ FEP 9898 resin provide the superior properties characteristic of fluoroplastic resins: 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, and excellent weather resistance.
In a flame situation, products of Teflon ™ FEP 9898 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.
