DuPont ™ Teflon ® PTFE 640XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 640XT X offers the excellent combination of properties typical of the Teflon ® fluoropolymer resins: non-aging characteristics; chemical inertness to nearly all industrial chemicals and solvents; exceptional dielectric properties, stable with frequency and temperature; toughness and flexibility; low coefficient of friction; non-stick characteristics; negligible moisture absorption; excellent weather resistance; service temperature up to 260°C (500°F); useful properties at -240 °C (-400 °F); Teflon ® PTFE 640XT X is designed for processing over a wide extrusion reduction ratio range (250:1 to 5000:1), with excellent performance even at the top of this range. Due to its outstanding transformation characteristics, Teflon ® PTFE 640XT X can be extruded with very low lubricant levels over a wide reduction ratio range, while the extrusion pressure remains low. For example, Teflon ® PTFE 640XT X can be extruded into wire with excellent performance in the reduction ratio range of 1000:1 to 4500:1 with a single lubricant level of 16% (based on total weight). This means that a single PTFE/lubricant mixture can be used for many constructions being manufactured in the same size extruder line. In addition, the excellent high reduction ratio performance means that products made in small-bore machines with other lower reduction ratio rated fine powders can now be extruded in larger ones, which represent a considerable economic advantage, since more material can be extruded per extrusion. This also means that longer lengths of wire or tubing can be achieved in one extrusion. Teflon ® PTFE 640XT X meets the requirements of ASTM D 4895-10, Type I, Grade 1, Class C. Typical Applications Teflon ® PTFE 640XT X is mainly used for insulation of high-performance wire and cables, as well as tubing. It is also suitable for other typical applications such as additives where some properties of PTFE are required.
