Applications for Teflon™ FEP 8787 include small diameter, thin wall wire and cable insulation.
Description
Teflon™ FEP 8787 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 good electrical properties, Teflon™ FEP 8787 has been specifically designed for high-speed extrusion of thin insulation layers on small-gauge wires. Table 1 shows the typical property data for Teflon™ FEP 8787.
As shown in Table 1, this resin provides the electrical and mechanical properties needed for low voltage applications. In addition, Teflon™ FEP 8787 has a higher melt flow rate than most other fluoroplastic resins. This permits higher extrusion speeds and easier processing, making Teflon™ FEP 8787 a cost-effective alternative for producing thin-wall extrusions.
Teflon™ FEP 8787 is designed and made to have improved dissipation factor at high frequencies, and to have significant plate-out resistance in melt extrusion. Teflon™ FEP 8787 is used when traditional extrusion 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 8787 can be used to improve processing rates. Teflon™ FEP 8787 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon™ FEP 8787 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.
Teflon™ FEP 8787 is designed for applications that require only minimal flex life or stress crack resistance. Chemours provides a wide range of FEP and PFA grades designed to meet a variety of manufacturing productivity and end-use performance requirements. Consult with your Chemours sales representative for grade recommendations about suitability for a specific application, especially if there is a concern about flex life or stress crack resistance.
