DuPont ™ Teflon ® PTFE 605XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 605XT 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);
- moderate stiffness and high ultimate elongation.
Teflon ® PTFE 605XT X is designed for processing at low to medium reduction ratios of 10:1 to 300:1. It is particularly suitable for unsintered stretched products and for sintered products with high mechanical properties.
Teflon ® PTFE 605XT X meets the requirements of ASTM D 4895-91a, Type I, Grade 4, Class A.
Typical Applications
Teflon ® PTFE 605XT X is mainly used for unsintered articles including filter membranes and gaskets. It is also used for making sintered products such pipe liners and tubes.
