Teflon® PTFE 641XT X
Description
Teflon ™ PTFE 641XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ™ PTFE 641XT X offers the excellent combination of properties typical of Teflon ™ fluoroplastic resins:
Teflon ™ PTFE 641XT X is designed for high-speed processing over a wide extrusion reduction ratio range (250:1–5000:1), with excellent performance even at the top of this range. The key feature of Teflon ™ PTFE 641XT X is the enlarged operating window over high extrusion reduction ratios, allowing a more robust extrusion process. This can translate in increased extrusion line speed and/or longer flawless wire length. Due to its outstanding transformation characteristics, Teflon ™ PTFE 641XT 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 641XT X can be extruded into wire with excellent performance in the reduction ratio range of 1000:1–5000:1 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, representing a considerable economic advantage, as 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 641XT X meets the requirements of ASTM D4895, Type I, Grade 1, Class C.
Typical Applications
Teflon ™ PTFE 641XT X is mainly used for insulation of high-performance wire and cables, as well as tubing.
