| Teflon® PTFE 605XT X | |||
| Polytetrafluoroethylene | |||
| Product Description: | |||
| 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. | |||
