Teflon®C PFA 510
全氟烷氧基
DuPont Fluoropolymers
产品说明
Teflon®C PFA resins are available in 2.5-mm (0.1-in.) pellets.
These fluoropolymer resins (perfluoroalkoxy) combine the chemical and high
temperature resistance of Teflon®PFA with antistatic levels of electrical conductivity.
Properly processed products made from Teflon®C PFA resins provide the superior
properties typical of the fluoropolymer resins: retention of properties after
service at 260°C (500°F), useful properties at -196°C (-320°F), and chemical inertness to nearly
all industrial chemicals and solvents. Molded products have moderate stiffness,
excellent toughness, low coefficient of friction, nonstick characteristics,
resistance to creep at high service temperatures, and excellent weather
resistance.
These resins can be processed by traditional extrusion
and molding processes. They have high melt strength and thermal stability at
high processing temperatures.
Three grades of Teflon®C PFA resins covering a broad range of
Melt Flow Rates (MFR) are available. The low MFR resin provides a higher degree
of stress crack resistance while the high MFR resin is easier to process.
