备注说明 | Typical ApplicationApplications for DuPont™ Teflon® FEP 9475 include small diameter, thin wall wire and cable insulation; industrial film; and intricate or thin wall parts made by injection moulding.DescriptionDuPont™ Teflon® FEP 9475 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, Teflon ® FEP 9475 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, Teflon ® FEP 9475 has a higher melt flow rate than most other fluoroplastic resins. This permits higher extrusion speeds and easier processing, making Teflon ® FEP 9475 a cost-effective alternative for producing thin-wall extrusions. Teflon ® FEP 9475 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 9475 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 9475 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. Teflon ® FEP 9475 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon ® FEP 9475 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 9475 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. |
