Technical Data
產品說明
Teflon ® PTFE 8A X is a free-flowing white powder composed of relatively large particles. It has high bulk density and good powder flow. It's most unique features are improved moldability at lower pressure and improved surface smoothness of finished parts. The high bulk density and low compression ratio of Teflon® PTFE 8A X permit the use of shallow molds for small parts and complex shapes. Good powder flow is necessary for use in equipment that feeds resin automatically, and for filling deep and narrow molds that are pressed isostatically. Reduced pressure is an advantage for moldings with large surface area and for isostatic molding. Teflon ® PTFE 8A X is often preferred for molding thick sheets and for isostatic moldings. It is sometimes used for ram extrusion of rod and tubing with thicker cross sections. Properly processed products made from neat Teflon ® PTFE 8A X provide the superior properties typical of the fluoropolymer resins: retention of properties after service at 260 °C (500 °F), useful properties at -240 °C (-400 °F), chemical inertness to nearly all industrial chemicals and solvents, and low friction and antistick surfaces. Dielectric properties are outstanding and stable with frequency and temperature. Molded products have moderate stiffness and high ultimate elongation. In a flame situation, products of Teflon ® PTFE 8A X resist ignition and do not themselves promote flame spread. When ignited by flame from other sources, their contribution of heat is small and with very little smoke. Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions.
Typical Applications
Many end products are fabricated from moldings of Teflon ® PTFE 8A X, including small parts such as ball valve seats, seals, discs, and lab ware. Thick molded sheets are stock shapes made from Teflon ® PTFE 8A X. It is also chosen for lining pipes, valves, and valve plugs—and for ducting, expansion bellows, piston rings, and other large complex moldings.
