Teflon® FEP 9819FL
Teflon ™ FEP 9819FL is a specialty fluoroplastic resin available as a loosely compacted fluff.Teflon ™ FEP 9819FL and the other Teflon ™ FEP (fluorinated ethylene propylene) copolymer resins combine the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene (PTFE). They have high melt strength and stability at recommended processing temperatures.
Teflon ™ FEP 9819FL is preferred for products that are not exposed to severe environmental stress in service. Properly processed products made from neat Teflon ™ FEP 9819FL resin provide the superior properties typical of the fluoroplastic resins: retention of properties after service at 204 °C (400 °F), useful properties at –240 °C (–400 °F), and excellent dielectric properties and chemical inertness to nearly all industrial chemicals and solvents. Table 1 shows typical property data for Teflon ™ FEP 9819FL. Molded products have moderate stiffness and high ultimate elongation. In a flame, products of Teflon ™ FEP 9819FL resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and is added at a slow rate with very little smoke.
